Can any one give me a list or recommendations of board assembler / manufacturers (Southeast U.S. prefered) who could handle assembly of 2 inch x2 inch PWB with 100+ surface mount components. No testing required. I would appreciate any help or recomen

We have big issue in SMD drop during assembling and detection of this kind of foreign materials on the PCBAs.

Does your assembler have to be located in the South-east? We are located in Northern California and offer assembly services with high turn times. Please contact: C.Y. Ong O-Tech 415-642-1939 otech@flash.net

Where in the process? Pick and place should know when it drops something and stop. If during reflow you need to work out why something is dropping/being blown off and solve that issue. And the only reliable way of catching that is going to be AOI.

During the movement of the placemat head, components drop on the PCB. Sometimes machine doesn't give error massage for drop component. How to manage additional components detection in 2D AOI?

Typical is 4 to 6 degrees inclination.

Hi Ken What exactly the best reffered angle for Sn/Pb & Pb-free soldering? Is there a site where I can read the basic engineering concepts about this topic?

About the anlge typically is 5-7 depending on the machine. If solder smt components, the best is to use (swich on) double wave machine - (swich on both) chip and laminar wave. Regards.

Hi, I`m thinking what would be the best way to avoid icicles on lead free solder!

Hi, I see that the wave angle of the wave solder machine takes a major part on soldering SMDs if they are assemlbed with glue. To avoid the shadowing effect and bridging what would be the best angel of the wave for Sn/Pb & Pb-free soldering processs
