Tried and True is counting your components if there is any indication of loss... this is a great TOPIC... unfortunately there are many ways to lose components. Feeder setup,problems with a feeder while in the machine(IE mylar problems or wrong step)

Hi Another add, This depends on your application environment. If you have levels of shock and vibration or high thermals underfill is needed. YiE, MA/NY DDave

Hello folks, Just wondering if there is a guideline out there that specifies how many temp/humidity sensors are needed in a certain unit area size in PCBA assembly production, especially for the SMT process. Thanks! Henry

Very good consultant answers. Has anyone evry really used T&H data to ever determine fallout? I've seen it recorded many times over the years, but all it does is take up floor space to store the charts from the recorders.

Walt; How can I say this politely...Garth used to work for me. His enthusiastic support of the APS machines was not based on reality. We have had so many problems with our 2 machines that we are getting rid of them. I hope you make out better. G

Many companies used the Fuji CP-4 and CP-6 chip shooters, these are good for the small components like resistors, caps, diodes, transistors and small IC's. If you have BGA, QFP or other larger odd components you will need to go with another type of

Hi I prefer reading piles of stuff from many sources, yet George does a reasonable job. DrFlipChip.com I understand the next SMTA in Boston will cover this and their are other web sites. YiE, DDave
