MSL 3 means you can have the devices open for a maximum of 168 hours in an atmosphere of less then or equal to 30 C and 60% RH. If the humidity is less then 60% then it means the devices will absorb less moisture in a given time, but even at 40% RH y

@ Sr.Tech, Any voiding means that the part of the package under the void is not forming a solid thermal interface with the PCB, therefore it's heatsinking capability is reduced. With the drive for smaller packages with higher power handling capabil

People. We have a Malaysian subcontractor who says that he can't find anyone to re-ball a 528 pin BGA device. Does anyone know of a company who can re-ball this device for them. Thanks for your help. Steve.

Greetings. Does anyone know of a good reference on the proper physical handling of surface mount devices? We have a number of very small builds, so our stockroom is very often issuing single piece quantities. The parts are protected from ESD, but

Use your board supplier recommendations Specific procedure or guidelines that need to be followed for handling Moisture Sensitive Devices => J-STD-020 & J-STD-033 Is there any paste height/volume requirement for a lead-free process? => You need to

| Having implemented the process of handling moisture sensitive devices our logistics department tries to classify all parts according to their moisture level. | Going through datasheets wasn�t that helpfull, so does anyone know of a source for that

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

I could not find a specific clause or section in J-STD-001B which can relates to special requirements in storage, packing and handling of Moisture sensitive devices per J-Std-033 / 786A /-022 . I guess the way ESD is relevant to electronics assemb
