Also company B may have far higher overheads to support - sales guys, directors, accountants etc. They may also be set up for longer runs so as Ms Chunks previously mentions, the set up & teardowns would also incur the opportunity cost of not being

Use ENIG, plated finish will be too thick and make for a brittle joint. ENIG is self limiting so this condition cannot be present. To ensure that the bond is strong for BGA you must ensure that process is under control. The correct reflow profile w

I have a PC graphics card that has a damaged component and I have no clue what it is. The other two that look identical are black flat top with which looks like a mini copper coil in the middle and two leads on each side. They are the last componen

You are going to struggle with that sort of connector - the only pin headers that seem to have widespread sucess are the dual inline ones with bent over j leads that sit on the board. They come with a plastic hat that allows vacuum pick up. However
