Hello all, I have been tasked with bringing my company up to spec with J-STD-033, yes lucky me! My question is this: While I was searching the Web for suitable suppliers of dry cabinets I came across a company advertising a humidity control system f

Michael, This concern is well covered in J-STD-033, section 8.6 Board Rework. "...If the component temperature exceeds 200C, the board may require a bakeout prior to rework..." In other words, you only need to worry about moisture related defects w

Three LEDs, 3.5volts @.02amps each is 10.5volts. You said you calculated out an 82 ohm resistor so 82 ohms * .02amps is 1.64volts, I guess your going to use a 12volt supply. P=I*E =.02amps * 1.64volts =.033watts so a .25watt resistor will be fine

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

J-STD-033A specifies a 1 year exposure life for moisture sensitive level 2 components, but no baking temp/duration for anything less than a level 2a part. Although the need is rare, what does a person do to dry a level 2 part that has been exposed f

Hi Bryan, I hope you dont mind a quick sales pitch here. We have developed a system called HumiTel which is used to manage MSDs. Its not the paper tracking system you mentioned; it comes in two flavours, a hardware tracking device and a software whic
