Hi Mike, The Hadco design guidelines are really good - I was just there. To expand on what Dave said, scoring is an option, but I've never had good luck with it, myself. The scores are either too shallow, and I can't break the boards easily enough

Information a SIR test vehicle can be found in IPC-9201, SIR Handbook [http://www.ipc.org]. Common test boards are: * IPC-B-24 (copper and HASL, FR-4 and polyimide) * IPC-B-36 (bare copper and HASL, FR-4 and polyimide) * IPC Phoenix board (bare copp

After saying for years that we'd never do two-sided assembly, the powers that be are not only saying we will, but they're threatening to throw an out of house design at us...no frame (it's a PCI card with a couple of dinky breakaway tabs), no tooling

Fids ON the PCB will have a reference to the PCB 0,0 point in CAD data generally or can be measured with good accuracy in gerber if CAD is not available. Panel fiducials are not always referenced from the PCB 0,0 point but many times are referenced

We need some opinions about a situation that is causing problems in our process. The pcb's in question are .125 thick with a HASL finish. The boards are coming in with a large amount of solder trapped inside the via holes. Sometimes this solder is ac

Ok, help me out here guys and gals...... I have never understood the concept of scoring on mixed technology or SMT boards. It is quite obvious to me that the potential for SMT solder joint damage through the mechanical stresses of breakout are high.
