Assuming that you need information such as the type and size of screw to the recommended torque value. I have found great information from the torque tool manufacturers themselves! There is an ANSI spec but I don't know the specifics. Your torque d

I wuld say it is attachment method and post install force that is the problem not the size of the heatsink. we place heatsinks that are at least 5 times the size of BGA with no issue, they are attached with very precision torque drivers. Russ

Hi Experts, Here in Box builds area, there was an argument on frequency of verifying torque reading. Shiftly changed to daily and now we are changing it to weekly. The reason for relaxing this frequency is b'cos the data we collected shown that the

Bud, hard to say without looking at bom / drawings & what manning you have avaiable to figure out what you need to put in place to get the build rate you need. is the cabinate supplied as is or do you have to build that as well? You'll need some ele

I'm wrestling with the infamous adjustable torque drivers on the production floor. Despite a procedure that clearly forbids it, we still have the occasional know-it-all that will just crank the knob until the desired setting is visible in the windo

While I don't understand why, this topic comes-up fairly often on SMTnet. [That the topic recurs indicates there truely is a problem and I'm just too doopy to understand it.] Several things: 1 Check the fine SMTnet Archives. 2 Some glue suppliers kn

We did weekly and monthly. Final assembly (Heavy use) recieved weekly. Field service area, sub assembly, low volume, ..... we went monthly. I wrote the ISO specs to read "Calbration of screw drivers to be monitored and logged"( this Simplified of

We find that the raw BGA's pad sheared surface has the SnPb solder at various Z heights whereas the assembled BGAs pad leave a smooth layer of SnPb along the pad. Like to understand the cause for the difference. Who could guess? Solder joint streng
