PCB制程能力要求PCB制程能力要求(Printed Circuit Board Process Capability Requirements)是指评估和控制印制电路板(PCB)制造过程中各项关键参数的能力和稳定性的要求。
这些参数包括材料选择、设计规范、加工工艺以及质量控制等方面。
PCB制程能力要求的好坏直接影响到最终产品的质量和可靠性。
首先,材料选择是PCB制程中的重要环节。
材料的选择应根据设计要求和应用场景来确定。
常见的PCB材料有FR-4玻璃纤维层压板、聚酰亚胺(PI)板、塑料CCL以及金属基板等。
不同材料拥有不同的性能和特点,制程能力要求应确保所选材料符合设计和质量要求。
其次,设计规范也是PCB制程能力要求的关键内容之一、设计规范涉及到PCB板的层次结构、线宽线距、焊盘剂量、排布规则等方面。
设计规范应与PCB制造过程相匹配,确保制造过程的可控性和稳定性。
设计规范的好坏直接影响到PCB板的制程能力和产品性能。
加工工艺是PCB制造过程中的核心环节。
加工工艺涉及到PCB的制备、成型、打孔、切割、压装、钻孔、镀铜等。
制程能力要求应确保加工工艺的准确性和稳定性,以确保PCB板的精度、可靠性和耐用性。
质量控制是PCB制造过程中的重要环节。
质量控制涉及到PCB的各项指标的测量、分析和监控。
制程能力要求应确保质量控制的有效性和稳定性。
常见的质量控制指标包括PCB板的尺寸误差、线宽线距误差、板厚误差、表面光洁度等。
针对这些要求,制程能力评估是评估制程能力的方法之一、制程能力评估是通过对制程数据的统计分析,确定制程过程的稳定性和可控性。
常见的制程能力评估方法有过程能力指数(Cpk)、过程性能指数(Ppk)、过程交叉性能指数(Pp/Ppk)等。
针对不同的应用场景和要求,PCB制程能力要求也有所不同。
例如,在高频应用中,对PCB板的信号损耗和传输特性要求较高;在高可靠性应用中,对PCB板的可靠性和耐用性要求较高。

PCBA Quality Process AuditInformation and InstructionsRev. 3 PURPOSEThis document was developed as an Audit Tool to assess PCBA Manufacturing Process Capability.本文件用來作為評估PCBA工厂制程能力的Audit工具.It is intended to provide an assessment of PCBA Manufacturing Capability based on PCBA Manufacturing Complexity.此文件的目的, 是提供一個基于PCBA制造复雜性的對PCBA制程能力的評估方法.Less complex PCBAs will not require the same manufacturing capability as more complex PCBAs.較簡單的PCBA並不要求其具有跟較复雜PCBA一樣高的制程能力Thus by matching capability with complexity, the most economic manufacturing solution can be determined for a sustained quality performance.因此, 通過制程能力与PCBA的复雜性相匹配, 就可以采用最經濟的制造方法達到持久的品質效能.The tool may also be used to assess RMA/Repair Capability.這個工具也可以用來評估RMA和維修能力.A qualified auditor may also use this tool as a guideline to conduct a process 'Gap Analysis' based on product complexity.合格的稽核員也可以用這個工具作指導對一制程進行"缺陷分析(Gap Analysis)", ----應根据此制程所生產產品的复雜性來進行.SCOPEThe PCBA Audit Document is primarily intended to be used for suppliers/manufacturers of PCBA Products for Dell.此PCBA稽核文件供DELL公司的PCBA產品供應商/制造商使用.The audit document may also be used to assess the manufacturing process for any PCBA that is incorporated into a Dell assembly.此稽核文件也可用來評估任何在DELL組裝中使用的PCBA的制造制程.When used to assess RMA/Repair Capability, the tool may be used at any location where RMA/Repair activity takes place.當用于評估RMA和維修能力時, 無論RMA和維修在哪里進行, 此工具均可運用.PCBA COMPLEXITY and CAPABILITY MATCHINGPCBA复雜性和能力匹配The SQE Auditor will decide what PCBA Complexity category to audit a supplier facility or potential supplier facility against.由SQE稽核員決定對供應商工廠或潛在供應商的工廠适用哪個級別的复雜性等級.This determination is made based on the complexity of the PCBA product to be outsourced or evaluated這是基于PCBA產品的复雜性決定的.To do this, the complexity of the product must first be calculated using Dell Tool COR.40.WWP.SQ.0229. This is available on Valuechain.為了決定适用哪個复雜性等級, 首先須用DELL TOOL COR.40.WWP.SQ.0229這個工具對產品的复雜性進行評估. 這可以在Valuechain上取得.Knowing the product complexity, it is then possible to use this tool to make an assessment of the line installed for a product of that complexity.知道了產品的复雜性, 然后才可能用這個工具對生產此复雜性的產品的生產線進行評估.There are 10 categories of complexity used by Dell, ranging from 1 (Most Complex) to 10 (Least Complex).DELL所用的复雜性种類分10個等級, 范圍從1(最高复雜性)到10(最低复雜性).In this audit, complexity categories are grouped into five categories as can be seen on the individual audit worksheets.但在此稽核中, 复雜性等級被合并成只有5種, 這在后面的各個稽核表中可以看到.AUDIT BY SELF ASSESSMENT自我稽核A supplier's facility is required to complete a self assessment using this tool in advance of the Dell Audit.要求在DELL稽核之前, 供應商用這個工具進行自我評估先..)It is expected that during the self-assessment process, that the supplier will use this opportunity to ask questions for either clarification or to better understand intent of the audit criteria. Waiting for the formal Dell audit to ask these types of questions is too late. It is also expected that based on self audit results, a supplier will inform the Dell team of their readiness for a formal Dell audit.DELL希望供應商在自我評估的時候問那些不太清楚或是對此稽核標准比較深入的問題. 等到DELL正式稽核的時候來問, 將顯得太遲了. DELL也希望供應商基于自我稽核的結果, 來通知DELL他們是否已准備好了.A self assessment is completed by adding a score to the relevant column in each worksheet once product complexity has been determined.确定了產品的复雜性, 就可以進行自我評估了. 每完成一項評估, 就在相應欄位打上分數.If a facility has multiple lines building Dell product of the same complexity, the supplier shall ensure all lines are available to be audited.如果一個工廠有多條線生產同一复雜性等級的DELL產品, 供應商應保証所有的線都可以被稽核.The SQE Auditor will randomly select one line to be audited for the product complexity to be assessed.對某一复雜度的產品, SQE稽核員將隨机選擇一條線稽核.During the audit process, the Dell SQE may wish to review every question/criterion listed on the audit document, or alternatively the SQE may chooseto focus only on those questions for which the supplier awarded themselves a score of 1 by self-assessment. The path taken is left to SQE discretion.稽核過程中, DELL SQE會稽核列在此稽核文件上的每一個問題/標准, 或者會只集中于供應商在自我評估中給自己打了" 1 "分的項目, 具体如何作, 由SQE自己決定. The score awarded by the SQE Auditor will be entered in the 'Actual' column on each worksheet.SQE稽核員所打的分輸入每張工作表的 "Actual" 一欄In this way the delta between the self assessment and the actual score is known. The size of this delta is a measure of audit preparedness and understanding. The difference between "self score" and "actual score" will be approximately 5% if preparation and understanding is good.這樣, 就可以看出自我評估与實際分數之間的差別(用delta表示). 差別(delta)的大小量度出了供應商對這份文件的理解程度和對這次Audit的准備程度. 如果對DELL QPA理解得好並作了充分准備的話, 自我評分与實際分數之間的差別大約會是5%.AUDIT RESULTS稽核結果The SQE Auditor must complete at least 6 of the 13 processes before an Audit Result can be declared.SQE 稽核員至少應稽核完本文件列出的13段制程中的6段, 否則不可以發布稽核結果.It is strongly recommended that all 13 sections of the audit be completed for suppliers who have no previous experience with manufacturing PCBAs for Dell or for existing Dell suppliers who are attempting to build a higher complexity PCBA product for the first time.強烈建議那些以前沒有為DELL制造PCBA經驗的供應商或是DELL的既有供應商但卻是第一次制造更高复雜度的產品時, 應全部完成13個部分的稽核.The overall process average result determines the Audit score achieved for the PCBA Supplier assessed.PCBA供應商取得的分數由全部制程稽核的平均結果決定.The 'Pass' score for the Audit is 80% for all PCBA Products irrespective of complexity.任何PCBA產品(無論什么复雜度)的'PASS'分是80%.If an overall process average score of equal or greater than 80% is achieved, and no individual processes have failed, a 'Pass' result is awarded.如果全制程平均分等于或大于80%, 并且沒有單項制程fail, 就可以得到'PASS'.If one or more individual processes have failed, but an overall Audit score of equal or greater than 80% was achieved, either a "Conditional Pass" or a "Fail" Result shall be awarded. The determination of this audit result is at the discretion of the Lead SQE Auditor, based on the severity of the issues for any of the failing sections. If the overall process average score is less than 80%, a "Fail" result is awarded.如果有一個或多個制程fail, 但總的稽核分數仍等于或大于80%, 結果將是"條件性PASS"(Conditional Pass)或"FAIL". 究竟給那個, 由首席SQE稽核者根据fail部分問題的嚴重程度決定. 如果全製程的平均分不到80%, 那么結果就是"Fail".NOTE: An individual process fails when the section score is below 80% OR if an "non-negotiable" question scores 0. (see "Audit Mechanics" instructions for additional information.)備注: 當分數低于80%或只要有一個"必達" 項分數為 0, 此項製程就得"Fail".If a "Conditional Pass" or "Fail" Result is awarded, a Corrective Action Plan is due from the supplier within two weeks of the date of audit completion.如果所得結果是"條件性Pass"或"Fail", 從稽核完成之日起兩周內, 供應商須給出改善計划(Corrective Action Plan).The Corrective Action Plan must contain a timeline to 'bridge' to a Pass status and must propose a target date for a Dell follow-up Audit.改善計划必須包含通向"Pass"狀態的分階段時間表; 必須給一個DELL下一次稽核的目標日期.Failure to achieve a Pass Result on the follow up Audit may impact business award decisions.稽核中不能獲得"Pass"結果將影響到DELL給供應商的商業回報決策(business award decisions).A PASS RESULTOnce a supplier's facility has passed the Audit for a particular product complexity, the facility's process is approved for all products of that complexity.如果供應商的工厂通過了對某一复雜度產品的稽核, 那么此工厂的製程就可以生產所有此复雜度的產品.Thus, the facility has proven their capability to build a product of that complexity for the line audited. As long as the same process capabilityis deployed for any new lines, there is no need to do 'official' audits for any additional lines added for product of that complexity.通過了稽核, 就証明這家工厂具備了在所稽核的生產線上生產此复雜度產品的能力.只要此製程被應用于新的生產線, 就不必對新增加的同樣生產此复雜度產品的產線再作"正式"的稽核.NOTE: While it is not an 'official' requirement to use the audit tool for additional lines, it is strongly advised that the SQE utilize the audit tool to verify that the capability of any new line is matched to the existing capability of the existing lines for a given PCBA complexity.備注: 對新增加的生產線, 雖然不"官方地"要求用此工具專門稽核, 但是強烈建議SQE用此稽核工具去确認對一既定复雜度的PCBA來說, 新線的制程能力是否与已存在線的制程能力相當.NOTE: For the purpose of "proven capability to build a product", a "facility" is defined as the same physical building, AND the same product complexity, AND the same supplier production and quality management team resources.備注: 為了闡述"制造一种產品的已獲証明的能力", 一個"工廠", 定義為: 位于同一棟建筑物內, 具有相同的產品复雜度, 具有同一供應商的生產和品質管理團隊資源.If a facility is approved for the most complex PCBA product, this does NOT necessarily mean they are automatically approved for all less complex products at that facility. Regardless of product complexity level, any test processes related to a new product should be audited because test processes are unique, based on product type, not PCBA process complexity.如果一個工廠已經被認可生產最复雜的PCBA產品, 這並不一定意味著在那個工廠生產較低复雜度的產品就自動獲得認可. 不管產品的复雜度等級, 任何與新產品有關的測詴製程都應予以稽核, 因為測詴制程是獨特的, 它基于具体的產品類型, 而不是PCBA的制程复雜性.An Audit will need to be conducted to ensure the capability deployed at least meets the minimum requirements for the less complex product.需要進行一次稽核, 以确保配置的能力至少符合較低复雜度產品的最低要求.AUDIT MECHANICS and QUESTIONS稽核机制和問題The Audit breaks down the PCBA Manufacturing Process into individual process steps, each of which is represented by an individual worksheet.此稽核把PCBA制造過程分成一些單個的制程, 每一單個制程都用一張單個的工作表進行說明.Within each worksheet is contained a series of questions specifically pertaining to the process being examined.每一張工作表都包含一系列特定的与此段制程有關的問題.These questions are focused on evaluating Process Disciplines, Control Methods, Process Capability/Technology, and Attention to Detail.這些問題集中于評估制程素質, 控制方法, 制程能力/工藝, 並關注到細節.The questions were devised and developed as closed questions with every attempt to avoid ambiguity.這些問題經過設計和發展已經穩定下來. 為了避免問題歧義, 我們已經盡了所有的嘗詴和努力.Because of the closed nature of the questions, there can only be one of two answers to any question, i.e. Yes (1) or No (0).因為這些問題具有穩定性, 每一個問題都只有一個确定的答案, 即: 要么是 Yes(1分), 要么是No(0分).Thus, the criterion is either fully met or it is not. If the Criterion is met, a score of 1 is obtained. If the Criterion is not met, a score of 0 is obtained.因此, 對一個標准, 要么是完全達到要么就是沒達到. 如果標准達到了, 就得1分; 沒達到, 0 分.If there is any doubt as to the score to award for any given Criterion, a score of zero shall be awarded by default.如果對一個標准的打分有猶豫, 那么這一項就默認為0分.Any Criterion that scores 1 shall be clearly demonstrated, followed, and be beyond reproach.任何得1分的項目都應有明确的証明, 領會, 并且沒有爭議.In the event that a supplier clearly meets the intent of the audit question, but does not exactly do what the question asks, a score of 1 shall be given.如果供應商明顯達到了稽核問題的意圖, 則即使沒有恰好地按此問題所要求的做, 也應給1分.There are cells within the audit document that are shaded in gray. These cells may be coded as Not Applicable (NA) under certain conditions.這份文件中有一些標成灰色的單元格, 這些格子在一定的條件下可以表示 "不适用(NA)".If coded NA, the denominator in the score percentage calculation will automatically be adjusted to account for this NA allocation to the cell.對編碼成NA的格元, 計算分數時會自動對其作出調整.The conditions under which NA may be allocated are as follows:-會分配作NA的情況有下面几种:1. NA may be allocated to a cell if the question is not applicable to the product due to some 'real' physical reason.1. 如果由于一些客觀的原因, 某問題不适用于某產品, 可以對其對應格元分配為NA.For example, if there are no MSD devices are on a product, then the questions pertaining to MSDs would be coded NA.舉例來說, 如果某產品上沒有濕度敏感元件(MSD), 那么有關濕度敏感元件(MSD)的問題就可以標為NA.2. NA may be allocated to a cell if the question is not applicable to the product because the physical product does not undergo a specific process.2. 有的產品會不經過某個制程, 所以有的問題就可能不适用于此產品. 這是就可以給其分配NA.For example, if there are no press fit connectors on a product, then the questions pertaining to the press fit process may be coded NA.舉例來說, 如果有的產品上沒有壓力適配插槽(press fit connector)的話, 那么屬于壓力適配插槽(press fit connector)的問題就將標識成NA.3. NA may be allocated to a cell if by answering some questions 'yes', other questions become redundant or irrelevant.3. 有時, 當對一些問題回答了'Yes'后, 有一些其它的問題就會變得多余或不再相關, 這時也會對一些格元分配'NA'.For example, if AOI is deployed, then the questions pertaining to Manual Inspection may be scored NA舉例而言, 如果用了AOI的話, 那么与人工檢查有關的問題就可以記作NA.Note 1: Not all gray shaded questions will be coded NA. The NA status is conditional on the above and SQE discretion.備注1: 並不是所有標成灰色的問題都是NA. 是否NA請參考上面的條件並取決于SQE的判斷.Note 2: Gray shaded cells are applicable when the process is deployed, and may still score zero if the above conditions are not satisfied.備注2: 如果標成灰色的格元所對應的項目, 制程仍适用, 就按正常的方法打分.For example, AOI is not required for complexity 5 PCBAs, but it may be deployed based on supplier preference比如, 复雜度5級的PCBA產品不要求AOI, 但是供應商可能會使用.If AOI is deployed, AOI questions must be scored 1 or 0, not NA.如果用了AOI, 那么有關AOI的問題就要么打1分要么打0分, 而不能打NA.Note 3: No other questions, other than those that have been predetermined by the gray shading, can be considered to be NA.備注3: 除了那些事先已經標示為灰色的問題, 其它問題的答案不可以是NA.There are certain questions in each section, (shaded in blue), that are considered non negotiable. In other words the question must score a 1.每一部分中都有一些問題(標示成藍色)是必達項, 即沒有商量余地的. 換句話說, 這些問題必須得1分.If any of these questions score a 0, then the process section under review will automatically fail, regardless of overall score.如果任何一個這种問題得0分, 那么此製程部分稽核結果就是fail, 不管總分是多少.For example, if the overall result for a section is equal to or greater than 80% and if any one of the "non negotiable" questions scored a zero, then the overall result for that section will be Fail, irrespective of the overall score.舉例而言, 如果某部分的總結果是等于或大于80%, 但是卻有一道"必達項"問題得0分, 那么這部分的總結果就是'Fail', 與總分無關.AUDITING A NEW SUPPLIER OR A NEW SUPPLIER FACILITY稽核一家新供應商或供應商的一家新工廠If a potential supplier or new supplier facility is required to be audited then the category to be completed in the audit document shallappropriately reflect the complexity of the product to be manufactured.如果一家潛在的供應商或供應商的一家新工廠需要稽核, 那么在此稽核文件中將完成的种類應适當地反映將要制造產品的复雜度.However, since such a supplier/facility will not be manufacturing a Dell product the SQE Auditor will have to select a line with a product whichmost closely matches the product to be manufactured and which is representative of the production line that the supplier intends to use to build Dell product.然而, 因為那樣一家供應商或工廠現在並未生產DELL產品, SQE稽核員將不得不選擇一條最接近于即將生產的產品的線進行稽核, 并且這條產線應該是供應商將用來建造DELL產品的典型的線.The SQE will not consider auditing a 'virtual' line based on some future installed capability.SQE不會考慮稽核那种"虛擬"的產線, 即計划在將來安裝但現在還沒實現的產線.AUDITING FOR RMA/REPAIR對RMA/維修的稽核This tool may also be used to assess capability of RMA/Repair facilities.這個工具也可以用來評估 RMA/維修的能力.All process highlighted on the Menu page are relevant for when it is necessary to conduct a Manufacturing Process QPA當有必要進行制造制程QPA時所有在'Menu'頁中突出強調(Highlight)的制程都与其相關.However, only those menu buttons highlighted in 'blue' may be used for a Repair/RMA QPA Audit.然而只有用'藍色'突出強調的菜單按鈕才可以被用來作為維修/RMA 的稽核.TRAINING培訓The PCBA Process Audit is very technical in content.PCBA制程稽核的內容非常具有技巧性.SQEs who use this tool are considered within Dell as being sufficiently qualified to conduct this audit.DELL用此工具作稽核的SQE都須經過充分的資格認証.To obtain this qualification, an SQE will have participated in at least three audits and lead a fourth under the supervision of a qualified auditor.欲獲得此資格, SQE至少需要參加3次實地稽核並在已獲資格稽核員的監督下主導一次稽核.SQEs wishing to use this tool should contact their regional champion to arrange for training, qualification and certification.希望用此工具的SQE應該通過以下三個步驟:首先聯系他們所在地的主管安排對其培訓, 然后進行資格認証, 最后取得証書.AUDIT SCHEDULE稽核安排The Audit may be used as and when the need arises. However, Dell will conduct an official audit at least annually for key suppliers. Before conductingan audit, the auditor must ensure the Dell commodity management team responsible for the relationship are advised of the audit schedule.只要有必要, 就可以Audit. 然而, DELL會對主要供應商每年至少作一次正式的稽核.稽核之前, 稽核員必須确保DELL產品的窗口管理團隊知道稽核排程表.It is also intended for suppliers to conduct internal audits by self assessment every quarter so progress may be reported to Dell.也希望供應商每個季度能作一次內部的自我評估, 並把進展情況報告給DELL.ADDITIONAL QUESTIONS其他問題Please contact Eric Hoh at eric_hoh@ for additional information or if there are any specific questions with regard to the technical content.如欲咨詢其它信息或有關于此文件的技術上的特別的問題要問, 請聯系Eric Hoh( eric_hoh@).REVISION HISTORY修訂歷程A00 Initial Release.

PCB制程能力要求PCB制程能力是指PCB(Printed Circuit Board,印刷电路板)制造过程中所要求的技术和能力。
它涵盖了从设计到制造的各个环节,包括材料选择、PCB设计、印刷、装配等过程。
制程能力的好坏直接影响到PCB的质量、性能以及稳定性,因此,掌握和提升制程能力对于PCB制造企业来说是非常重要的。
首先,制程能力要求需要考虑到PCB材料的选择。
PCB的材料直接决定了电路板的性能和可靠性。
常用的PCB材料有硬质纸质基材、玻璃纤维布质基材、陶瓷质基材等。
不同的应用场景对PCB材料的要求也有所不同。
例如,高频电路需要使用具有较小介电损耗和较低介电常数的材料,而高温环境下的电路则要求使用可以承受高温的材料。
因此,制程能力要求需要对不同材料的性能进行了解,并根据应用场景选择合适的材料。
其次,PCB设计是制程能力要求的另一个重要方面。
好的设计可以提高电路板的可靠性和性能。
在设计过程中,需要考虑排线的长度、宽度、间隔等参数的选择,以及掌握PCB设计软件的使用方法。
此外,还需要熟悉阻抗匹配的方法和原理,避免因为阻抗不匹配而导致信号衰减和干扰。
在PCB设计过程中,还需要保证设计的可制造性,即能够在实际制造过程中顺利实施。
因此,制程能力要求需要对PCB设计方面的技术和方法有深入的了解。
在PCB制造过程中,制程能力要求还包括PCB的印刷、装配等环节。
印刷过程需要掌握好涂布、曝光、脱模等技术,保证PCB上的线路图案的精确度和清晰度。
装配过程需要掌握焊接技术和检测技术,保证元器件能够正确焊接在电路板上,并且通过检测能够发现并修复可能存在的问题。
此外,在制程能力要求中还需要注意质量控制和质量管理的问题,建立完善的质量体系,确保生产出来的PCB具有稳定的性能和质量。
为了提高制程能力,并满足不同的要求,PCB制造企业可以进行相关的技术培训和知识更新。
培训可以包括PCB制造流程和工艺的学习,以及新材料、新工艺的掌握。
