4, printing required in accordance with process instructions carefully examined, to adjust to the poor; no abnormal before bulk printing;
5, check the print quality of the graphics content; defective products need to be cleaned after printing; printing quality can not be determined, the cross-squad processing;6, no abnormal before entering the next process.
Note:
1, P board inputs need to be carefully checked before printing the P plate surface without debris or P plate damage;
2, follow the principle of accessories;
Regular cleaning stencil; (solder paste printing cleaned once every 5-10PCS; the red plastic printing once every 10-50PCS cleaning)
4, the printed P board storage shall not exceed the number of 30pcs;

2, adjust the equipment rail mount placement machine procedures, equipment start automatic placement;
3, when the machine will alarm the material to make material after use to replace the material production;◆ preparation:
Every 15 minutes to view the remainder of the material in the production, when the material remainder is less than about 500, according to the name of the program station components installed in the feeder to remove the material from the specified material car placed on the preparation of the car.◆ refueling:
A machine alarm materials to make errors; confirm whether the alarm failure need to replace the material;
B, confirm the track number, unloading feeder find the need to replace materials; preparation car, looking for another person for material confirmation;
C, the packed material put into the unloading position of the feeder;
D, refueling and confirm to see the name of the material put into the machine and the machine feeding station name are the same;
E, according to the patch location map on the shape and direction of the replacement material to confirm.◆ Record:
Fill material to replace the record, refueling who was recognized signature confirmation.Note:
1, note that the integrity of the material name; such as: BL8503-30PRN ≠ BL8503-33PRN
2, pay attention to the material accuracy error; such as: 103J = 10KR ± 5% 103F = 10KR ± 1%; 103B = 10KR ±0.1%; commonly available error have ± 5%, ± 10% and -20% to +80% , respectively, with the letters J, K, Z;3, the operation of the equipment need to pay attention to safety, equipment operation objects of any kind shall not probe into the inside of the machine;
