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

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

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

We had a similar system on the Siemens machines, quite some time ago. However, it was not a laser light but a LED and a fiber cable. Actually the center fiber or receiver was surrounded by a bundle of small fibers for the LED light source. You may al

How is the component marked. Is it ink marked, laser marked or what? What is the material that the marking on? What volume are you looking at? We used a small, pencil-sized sand blaster, loaded with bicarbonate of soda to errode the mark off of plast

Has anyone ever looked into the possibility for laser marking 1812 size X7R ceramic chip capacitors injecting sufficient energy to cause cracking when voltage is applied? If so, what were the findings? We are having failures of caps from one manufa

I'd also recommend Control Micro Systems;4420 Metric Drive; Winter Park, Florida. We've been using one of their CO2 lasers for years to put a 2D code on our PCBs. 2D will save a lot of room and I'm told you can store more data. The laser drastical

Hi Mark, When we last checked out the laser systems you had to either use a solder preform or apply solder paste to the area, which meant either dispensing or some clever printing. Cheers, Rob.
