solder, but flux -> adhesive. Hmmmmm.... Are the chemists working hard to reduce the consequences of these possibilities? And as to Dave's comment about long term reliability issues due to outgassing from the adhesive, double-hmmmmmmm....... Ther

Placement jig which holds connector, SMD adhesive, profiling + low temperature paste. These are things I would research. If these can be fitted in SMT, than these should also be JEDEC standard. Datasheets will offer you any information you need to b

Joshua, 100um is 4mil aperture. You should ask several stencil houses about the possibility to print that small amount of paste(type 6 paste is available now with very small solder spheres 5-15um diameter). Even applying small amount(thin layer of f

Hi Francois, I made a recommendation to this question, some one else posted it earlier this month. I have done a little research and evaluated a couple of machines on site. If you require further information regarding the one I purchased for our comp

Peter, I have completed trials on various machines for cleaning both SMT stencils and misprinted PCB�s for solder paste and adhesive. Why do you have a preference with the cleaning solution, is this flexible? I can recommend a machine which we purcha

You may want to also try MRSI. They have awsome machines for bridging the gap between Semiconductor and SMT. They have an excellent research group and can answer a mojority of your questions. http://www.mrsigroup.com they are located in Mass, USA. Da

I would recommend pH neutral chemistries, particularly if a semi-automatic machine is to be used. There are many chemistries available. A partial list of chemistries that I have tested, and that are compatible with a variety of cleaning equipment i

Thank you for your annotaions. I am aware of the limits and temperatures of that material, but we are doing some research with thermoplastic base materials which won't survive standard solder paste reflow soldering. And beside of using conductive ad

One common practice, depending on what is on the other side of the PCB and how much heat you need to draw away from the part, is to manufacture a pseudo-heatsink into the board itself. It looks like a large tinned pad but has a dense array of vias f
