Hi John, I don't know of any posters etc. but specs. are available free on-line at www.jedec.com for classification, time out of packaging before baking is required, bake times & temperatures. My understanding is that it only causes a problem if th

I am looking at two different type fluxes, Kester 951nc and AIM 264-5nc. The two seem to be comparable, but the Kester is listed as an ORL0 and the AIM as a ROL0. My product builds are all military and I have been dictated to use only ROl0 flux. I kn

I was going to ask the same question. As was mentioned, it depends on the classification of product. If it's IPC Class 3, with a requirement for high reliability, I'd want the OEM manufacturer to have a defined statement on this issue for more that

In the past, black poly was used as a bridge between pink poly and shield bags because of slightly lower cost and offering some shielding as opposed to none with pink poly. However, as the price of shield bags continue to drop the usage of black poly

J-STD-001C just requires that the area not be so dirty as to contaminate your product, tools, workspace, etc. If you start counting particles, you're into cleanroom territory. Do a search on ISO 14644-1 for specifics. Actually Wikipedia does a ni

Handling requirements of all classifications of moisture sensitive devices is found in J-STD-033. It really isn't an issue for most parts unless they're going to reach reflow temperature again, which is unlikely unless you're removing a nearby compo

OR: Stands for organic (organic acid based flux) with the absence of rosin and/or resin. If you want to know everything about the classification of fluxes get the J-STD-004 �Requirements for Soldering Fluxes� at following link: http://webvision.ipc

Hi All, I was puzzled because of terrible blowholes in solder joints of gold plated odd-form components. I am very confused because all other components on the boards have perfect solder joints. Here are some process details: 1) Solder paste: N

Your ppl are correct, the capacitor is not sealed. So, it is perfectly acceptable for the capacitor to have absorbed moisture. If your ppl don't either prevent moisture absorption or remove the moisture prior to soldering, their component could fail
