CSP= Chip Scale Package, meaning small. A MicoBGA is a CSP, while a regular BGA is not a CSP. CSPs require fewer steps to fabricate than standard BGAs. A commonly quoted definition of a CSP is a package where the body size is

What i want to know is If we are using RoHS compliance component in Non RoHS process means leaded process is there any solderability issue ?

Good afternoon, Thanks for input AR. Fortunately, supplier can offer us nickel barrier alternative. I will do exactly as you did. BR, Pavel

Hi, colleagues! We only start using pb-free tehnology Our wave have foam fluxer What kind of flux would be best if we will use Sn100 solderbar What is your experience Best regards Peter

Maybe more baking time is needed. Topside board temp too low. Moisture trapped in board. Top of through hole capped by component and trapping flux. http://www.speedlinetech.com/electrovert/electrovert-troubleshooting/index.htm

If the solder joint meeting 8.2.5.4, minimum side joint length(D) and also meeting 8.2.5.6, minimum heel fillet height (F) but the heel fillet NOT extend to the mid point of outside bend. It is acceptable?

Check with your PCB supplier who the manufacturer of your I-Ag is. This makes a world of difference with regards to solderability.

Yes, all the leadfree solders are currently for consumer products. Military and aerospace industry haven't implemented leadfree yet. They are still study which to go! Maybe that time, we all can follow military std and having high reliability product

Or this might be the right solution Alternative lead free soldering reviewed: http://circuitsassembly.com/cms/content/view/4665/95/
