Try to insert thin copper plate (approx. 1.5mm thk) at the end of the flow direction. Place it approx. 2mm away from the lead. The copper will pull away the solder & thus minimise bridging problem.

Does anyone know of a less expensive technique to monitor board cleanliness (chlorides in micrograms/in2) other than omega mater - ion chromatography is costing us an arm and a leg.

Yeo, These are possible rootcause of that defect and you can evaluate. 1. Orientation of the capacitor, maybe the cap is located behind big component. 2. Reflow profile, check the profile on that side. 3. Yes, check also the mounting force. Philip

1. It is hard to tell, but your PCB vendor should test the PCB. 2. I think the important thing is the width of the apertures. You should have it laser-cut, and control the width no more than 90% of half pitch. Good luck.

The IPC-A-610 has the Acceptability requirements and the ANSI/J-STD-001 has the Requirements for soldering. Both deal with the requirements for the individual classes. Both of them are published by IPC and can be purchased in lots of places includ

Had cheacked the archives but I didn't see much about their comparison: 1. Throughput 2. Rework Rate 3. Effect on Placement Accuracy 4. Cost (cheaper or more expensive in the long term?) Has anyone compared the above. Please help me.

Two things: 1 Why isn't your assembly house correcting this problem? 2 Check the archives
