Slaine, thank you for sharing..

How compatible is SN100C wave on SAC305 hasl pcb or vice-versa?

Electronics Forum | Mon May 29 23:39:11 EDT 2006 | Faizal

Can anyone advice me on the effect of SN100C wave solder on SAC305 hasl board? I suppose the silver content on the hasl pcb would leech(contaminate) into solder pot.? Would it affect the surface bonding between copper pad and the solder.?

Is there some general file format for chip placement on pcb

The format is X,Y Theta of the component center for all placement machines. Gerber data can be useless, unless you have the reference from pin 1 to the component center. Some machines offer a CAD convertion tool. I don't know any machine, which can

I'm using a CIM software (http://www.aiscorp.com/products_npi_circuitcam.htm) to import gerber files and produce pick&place programs and paper/paperless documentation. It's very friendly, useful and fast, but not cheap. I don't know any other softwa
