Is anyone using a laser to selectively solder components to a board? I'm just starting to research selective soldering methods for the company i work for as we're looking to replace our current hand soldering processes for lead- and lead free- produ

If the goal is selective soldering (not to raise the substrate temperature too high), consider the use of microwaves. Our company has been working on this technology for selectively bonding substrates. For example, we use the process to bond ROHS met

Yes, PROMATION has customer's using laser to solder PCBs. This is too broad of a forum to discuss openly so please feel free to write me at: Gary_Goldberg@pro-mation-inc.com Perhaps I can assist Gary

My advice is the technology is not there unless your boards have been designed for laser soldering. Even then there are too many limitations to go into it. We tried a unit for almost a year and were never able to get consistent, not even going to m

Well, there seems to be many opinions, many of which could be correct, however... With the proper laser they can be quite good for soldering. Here are a few guidelines I would like to suggest. 1) Have your product soldered first (by the vendor) 2) T

I agree with James. Granted there are a variety of lasers to try, we too could not get a consistent power setting. Plus when paste turns liquid, you get some reflection. Also the mask around the pad has to be pulled back or burning may occur.

Hi, We are electrodepositing Au(0.25 to 0.5 microns) on Cu & using solder ball bonding process via laser.We are getting lots of voids within the solder (not kirkendall voids). Can anyone shed some light on this problem.We are not using any flux.Pre

Hello all, Does anyone here knows if it exist a special solder paste for diode laser soldering? What are the property that should have? Currently we are using a lead free solder with 2.5% flux. Thank you!

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 sol

Hello, This is what we currently use, lead free solder wire.
