Hi All, i have footprint 2X5 RA HEADER 2MM spacing in design. I am using about 9 mils of annular ring on top side and about 12 mils of annular ring on bottom side. refer picture attached. we are having solder short issues during wave solder so was

Hola... I'm in the middle of a project to reduce assembly time in one of our products, this product has a lot of TH connectors to be soldered by hand, I'm implementing PHIR, first run has been completed, the appearance of the solder joints are obvio

I don't know. We never had craziness like this before lead-free. You should have the yellowish-metal analyzed to be sure. Guessing: You're seeing this color on the terminations of components, not on the bulk of the SnX solder connection. If that's

Hi All, We leadform components for our assemblies in house and have been tinning the leads using a dip methood by hand into a solder pot. by just handling the components during the tinning and cleaning process we are at times damaging the parts/lea

Based on your knowledge and experience, could you tell me about speed differences when placing a mix of SMD at mass production? We could consider packages like the small R & C chips, then SOD323, SOT-23, SOT-23-5, SOT23-6, SON6, QFN8, SOIC-8, SOIC-16

Thanks Rob for your meaningful advice. Instead of just a general average time per component, I think if we have 3 averages, 1 per "component group", we will gain significant accuracy in the cost model. For instance, a motherboard may have 2500+ R and

Hi, If you can not rely on your programmer and the tools he uses then "double checking" can save you only materials but in time you really do not save often extend meaning. There are things you can identify before the stove, but if you use tools li

Our company has a process standard that requires a double person check at the beginning of every run (size of run is irrelevent, whether 20 panels or 500 panels). Every changeover that occurs a first piece inspection is made before reflow. If all is

Another interesting response! The PMTech machine looks interesting, but I doubt we will get clearance to spend this amount for a machine that doesn't get used several times daily. I wonder how much the Blundell machine is? Anyone have a costing for
