Hello, I am writing a software that deals with chip placement on PCB and I would like to know if there is some standart way to describe what are the coordinates of the chips on the pcb, I know that Gerber file contains all the drill holes and tracks,

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

I agree with Nick. You should check with the manufacturer to determine what type of plating is used on the components and see if the manufacturer has any recomendations on materials that may help. If no exotic materials are used, the culprit is most

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

I have used Multicore MP-100 and Heraeus F380 pastes for a while, and experienced very few dry joint problems. May be worth checking if the pad size and/or spacing are to the correct specification for the components. Check the date codes on the comp

1) The additional activity of the OA flux probably took care of the oxydation. How do you plan on taking care of the presence of conductive and corrosive residues from it now, though? You're not supposed to wash those parts with water. 2) The tomb
