The CCGA is like a BGA except that the columns are more square looking and there are many more of them. They are made of lead so they are very fragile. They are very expensive. There is a special cleaning process they have to go through once it has b

| A board shop rep contacted me about a process were solder paste is applied to the board as part of their mfg. process thereby eliminating the need for paste application at the assembler. This is a new one I have never heard of, but am willing to si

Does anyone have a list of component types that can be put on the bottomside of a doublesided reflow board that will not fall off during the second pass (Or on the otherhand, a list of components that will fall off)? This would be a list of parts tha

| I am having problems processing immersion gold boards. The achieved solder joints appear acceptable a la IPC-A-610, but the resultant joint does not fully cover the land, i.e. you can still see an outline of gold pad. | What is the best way to achi
