A client document mentions the following: "PCBA to comply with IPC class-2 guidelines, and performance grade 2 for components." What does "performance grade 2 for components" mean? Would appreciate your help.

We found a PCBA performance have insertion loss at the functional test process. We did some analysis and conclude the main root cause is from the PCB performance. What is the critical parameter in PCB will cause a failure in PCBA frequency performan

If it truly is a case of lazy workers who could perform better (faster), tie their pay and/or bonuses to their performance. The faster workers get a larger bonus than the slower workers for instance. Many different ways to implement the details but

Hi �Pb-Head� I agree with everything you say, except for your statement that alcohol based fluxes perform poorly with convection heat. The fluxes you tried might have performed poorly, but that doesn�t mean that all alcohol based fluxes perform poor

Hello marys, To determine the quality performance specification of your printers, dispensers or placement equipment, you must first know the operational accuracy and repeatability criteria from the equipment manufacturer. Only then can you determine

Siemens has an excellent reporting system. If you are running on Siplace Pro you can easily export the pick data and performance data to anaylize. If funds aren't an issue, look into the Siemens Explorer software, this will provide you with data,

Is there anyone performs solderability evaluation on PCB as a part of receiving acceptance criteria. It's costly to perform any form of physical evaluation whether simple as dip and look or wetting force balance. How do you have control in place to a

It has been mentioned that DPMO offers large advantages over First Pass yield calculations for measuring process performance!!regarding the same I have a few queries: What are the benchmarks for using DPMO as measures of process performance? How is

Inherrently there is this perception that the higher the density of components on an SMT assembly the better the machine performance. Would you stand behind this theory? I thought that I would, but I can't seem to prove it mathematically. By that
