Microflame vs laser soldering | 9 December, 2005

Dear Technetters

We have a unique soldering operation that needs automation and we will be evaluating various methods including laser reflow and Spirig�s Microflame. The actual soldering operation entails joing two metal contacts by depositing a solid solder deposit on one contact, applying flux, introducing the other contact and then solder reflow. The contacts are approx. 0,7 mm in diameter and 3,0mm long and the resulting solder connection is approx. 1,0mm in diameter. Any comments or experiences using either a laser, Microflame, focused IR or hot air for such an application are welcome.

Jim,

I don't have direct experience with the methods you mentioned but we have used induction heating in the past and is a very effective way to heat up metals quick. This method is also very easy to automate. I did a quick search as example http://www.rdoinduction.com/

Good luck Patrick

If it's metal to metal, use the flame. Laser has a lot of quirks to it.
