There are several types of lasers to do laser soldering. Panasonic also has a high intensity light that can solder as well. I've tried em' all and two over whelming things stand out when it comes to this type of soldering. #1 is preheat. It seems

Yes, kind of - I had a look through my notes from a while back where we did a lot of work on bending strenght but the only original source I could find was reference to a paper drawn up in 1979 "Increase Terminal to Pad-Peel Strength with a Standard

Some requirements to consider are: * Humidity and temperature controlled according to J-STD-001 * Electro-static discharge (ESD) control program according to ANSI/ESD-S-20.20. * Soldering technicians are trained and certified according to J-STD-0

Shear tests are [in my opinion] senseless. The shear stress you measure depends more on the shear rate and on the point where the force is applied than on the grain structure. When shearing a component, you not only apply shear stress, but also roll

Search the fine SMTnet Archives for previous discussion. This technique has been called 'pin-in-paste,' 'paste-in-hole,' 'intrusive reflow,' 'alternative assembly and reflow technology' and who can remember all the other consultant buzz-words. Look a

We agree with Rob. It looks like either kiss is blowing the paste around. It could be: * Nozzle id too large. * Kiss is occuring after the head has moved from the component. 0408%20MS%2001.jpg - Paste is not missing on the bottom-center pads. It is

I've recently pushed the company I work for to switch to a halogen-free solder that our supplier carries, Kester's NP 505 HR, prior we were using Kester NXG1. NP 505 HR performs great on the screen, we have a lot of down time in between prints (we d
