Another good source I've come to use quite often is the search engine from National Semi-Conductor. The link to the page is down below. If you ever run into a situation where you only know the company of manufacture for the chip, go to their web site

Electrically, the part still works, even if upside down. When upside down, you cannot see the part identifier. If you are an OEM and your QA/QC people don't freak out because they can't read the part, let it go. If you're a CM, your customer would

Before changing solder pastes or jumping through too many hoops, check the melting point of the 100 Sn (pure tin) connection. According to Kester, the melting point of 100Sn solder paste is 232 degrees C. If you do not reach that temperature, you wi

Assuming, you have nothing on the other board side, I would drill a hole through the trace and board with a step drill and a drill press. If you adjust the depth control carefully the wider step of the drill scratches the surfaces of the trace to mak

I realize that this is sort of off-topic, but do you have scads of solder beads (mid-chip solder balls, whatever you like to call them) with that stencil design? If not, would you mind sharing which paste it is that you are using? Email if you like
