I work for an electronics manufacture. Our end product is on PCBAs. My question is related to the use of safety glasses, which I know are required when doing rework. But here is the question: We ordered side shields for prescription glasses. Wha

Want to update this question a little, I know it appears few years ago, but I hope there is some updates... We have to assembly few samples of motherboards with this kind of finish (customer mistake during pcb order). Normally we can use leaded sold

Well the powers that be actually want to go with a regular rework station, for future growth. I guess they plan on using BGAs sometime in the near future. We're also planning on using a D-Pak device in this first board. So now we're looking at the

| There is a practise within the industry of an Inspector inspecting a board, and that same Inspector performing touch-up. My opinion is that the Inspection and Touch-up operations should be separate functions whereby the Inspector is not performing

Yes!!! How can we assemble boards with 20 pitch when we allow 0.008� error to the master art? Excellent question!!! IPC-D-300G has nothing to do with assembler requirements. It is written by and for fabricators, so that they can be comfortable.

For now, on this first board, we will be reworking components such as 0805 and 1210 size caps and resistors, along with SOT-23 and SC-70 size packages. We might eventually get into BGAs. This board will most likely be a double-sided board, probably

Steven, Try http://www.document-center.com/home. You will find various standards for BGAs freely-available but not for free. BTW, I have never seen a BGA underfilled. Only FC and CSPs. The standards available will explain when to.....High CTE delta

Multiple process and rework thermal cycles are brutal on boards and components. Improving reliability of products through reducing thermal stress ends-up being a major driver to the interest in lower MP LF solders. Binary LF solders require the addit
