This is a good idea. Heck, you could fill the bags with sand, if you wanted. Like anything else in the shop, bean bags require attention and maintenance. If you don't, eventually the seams on the bags loosen / break and you have to do a "clean-u

What is the surface finish of the PCB? Tin? Imersion Silver? What flux is used in wave solder and / or SMT? I have much experience with silver migration and tin wiskers. Both can disappear during a reqork cycle. Both can be extremely difficult

Levchek [ http://www.hexaconelectric.com/levchek.html ] is sold by Hexacon and most of the electronic assembly supply houses [eg, Technitool, HMC, Jensen, etc] Alternately, you can purchase heat tempered glass from your local glass store, but it wil

Vince Frank is probably not still here. Management at SMTnet chooses to keep all threads alive, turning a deaf ear to forum user requests to close threads after a reasonable period of time. The person that reopened this thread did so in all good c

Copper thieves...great idea...used some just today. How about some details on the wave soldering issues? I bet there are some mega-expert super brain-e-ax on here that would love to share their lifetime learned black art. Or maybe not (kidding).

I am fairly new to wave soldering and production processes, but I have been tasked with coming up with a calculation involving the shear strength of some through-hole leads. The leads are tinned copper and I suspect that tinning reduces the shear st

A nearby company specifies 'no wave soldering of second side SMT components' [er, words to that effect] to their CM. Among the the previous threads on SMTnet are: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=16944 http://www.smtnet.c

We are also having the same problem here. I was told earlier that it could be a problem with the solder mask during the raw board manufacturing level but then I noticed that the problem was only surfacing on boards that went through the wave. As far

Wave Solder temperature should not cause problem to MSDs. Just in case on PBA there are very critical MSLs (ie. 5 or 5a, 6 (?!?) try to detect what is the max temperature on such MSD bodies and how long they stay under such temperature. But it schoul
