DB Comments on things that should be set and controlled and not adjusted are: * We agree that pot temperature should be excluded. * We'd like you to add parallelism to your list of items to exclude from CK's list. It's given that parallelism is impo

The auditor may be using "verify" in an ESD Program context. See ANSI/ESD S20.20 [1999], 6.1.3, Compliance Verification Plan. It gives one definition of what the auditor may be seeking. For more on verification programs, look here: http://www.protek

To be more specific. I am actually talking about the electrical fatigue whereby a unit is undergo a cyclic electric test. Unlike thermal fatigue, it is all talking about temperature related testing, eg, ageing test, thermal cycle test, etc. Anyone of

DaveF, Our customer requirement is to comply with IPC-STD-001 but the J std doesn't specify the bake out temperature for populated boards and the moisture absortion rate. Right now we are baking the populated PWAs after aqueous wash at 80C at 18-48

I have an MSL3 part (a relay) supplied in tape and reel. From what I am able to determine, these parts require baking at 257 degrees F for a minimum of 8 hours once the integrity of the seal is broken for over 168 hours. How are parts baked at th

Oh, for a second there I thought it was 257 C, not F. Solder temperature! Still, one WEEK at 257 F seems way extreme. Maybe this is to bake out a part that has been underwater for a week. Is this a military part? I can't imagine any commercial-g

We're unfamiliar with such component dryout requirements. Commonly, tape & reel cover tape will seperate at 60*C. So, even if your baking on a metal reel, your should keep the bake temperature ~40*C. Sure makes you want to use these parts during th

Questions are: * Do not judge the quality of a solder connection by the shineyness or color of the solder connection. Do you have smooth and unform flow, no pitting, and good wetting to the lead and the pad? * What is the temperature of the leads of

I have been using sn100c for over a year now on our wave solder process and I am plenty satisfied so far. The secret for success with this alloy is to have your solder pot near 270 celsius and your dwell time has to be near 4 sec and your temperature
