2.5.3.3. Inspection Standard
If there is any issue of specification, direction and polarity, please follow process file to amend.
If the components are off, please adjust the file by following two methods
1) If the placement effects of all components are off in the same direction, it would be the fiducial issues. Please
resolve this issue by adjusting the coordinate of fiducials according to its value of deviation.
2) If there are several components off beyond allowance, you’d better adjust their coordinates on working file
with down-looking camera.
If there are couple of issues occur during test, some other points need to be considered.
1) Frequent pickup failure. Some suggestions are listed below,
2) The pick height is inappropriate, please revise the value after an inspection or a pick-test;
3) The pick offset needs an adjustment, it should be aligned with the center of component reel slot rather than
that of component.
4) Due to peel strength or installation issue of wasted film, the film on tape won’t be peeled completely
5) The nozzle was blocked
6) The nozzle is damaged or has a crack
7) The size issue of nozzle would cause air leakage or insufficient suction.
8) The air hose is blocked or has a leakage problem, and even the pump has an issue.
Frequently throwing components. Some suggestions are listed below,
1) Up-looking camera can’t take a clear picture of component due to brightness issue for example.
2) The pins are distorted
3) The size or shape isn’t aligned with that in “Footprint library’’
4) The size of nozzle is inappropriate or insufficient suction.
5) The nozzle has solder paste or rubbish cause air leakage
6) The nozzle is damaged or cracked cause air leakage
2.6. Continuous SMT Production
Follow the SOP to start production
Notes:
Do not touch the surface to board to avoid damaging the printed solder paste.
When the error message occurs, please checkout and solve it a.s.a.p.
Once reloading the component during production, pay attention to the model,specification,polarity and
direction of components.
Clear the trash box timely to avoid wasted materials stacked too high to damage the mount head.
