How about someone on a drum like they used to have in the bowels of a ship to control the speed of the unfortinuate ones that were rowing. The beat could be increased to speed up production or slowed down to adjust for a bottleneck. We had a manage

Ever been in one of those "rolling boombox" with the thumping bass shattering every windows a mile around? Those should be illegal, if only for the fact that the brains of the occupants is turned to jelly by the decibel levels. But my point was usin

Problems with the quality of hand assembly operations can be traced back to: * Poor investment in people training * Poor investment in process control * Poor investment in documentation and process instructions * Boredom and tedium Your potential in

As Russ says this should process well the BIG BUT..T is what are you using to process this part! How old / capable is your equipment. Screen print quality is a must. Placement accuracy is critical and reflow stability is important. So the answer is d

I am looking for a FPBGA adapter (pin 256 pitch 1.00mm size 17mm x 17mm). We need the adapter to interconnect the FPBGA from the handset board to a SW test board. Question: Where can I find BGA adapter with different heights? What do we have t

Hi In addition to what DaveF gave you which you should look at first Search the archives for warp bow twist warpage etc. A Lot of treads exist. Many of the larger OEM's and even the Mil have historically created their own documents for acceptable
