Bake your solder mask and then solder coat. If you are going to put an immersion finish like Osp, gold, tin or silver you would have to do a Micro etch to clean the copper prior to placing the surface finish. Regards, Board House

Can you just coat them with solder? Russ

A toaster oven is an improvement over hand soldering.

My company is currently using point source soldering of SMT components. We have seen some problems due to improper soldering and are looking to switch to a reflow oven/hotplate assembly. Our PCB's range in size but are no larger than 5"x5" and we as

Hi, I off center idea we used when we started. Get a pasta cooker, and put in vapor phase fluid, and then use that. Place the product in the bottom of the inner pot, and then heat on a small hot plate. When the vapor cloud gets high enough and the

90% of the battle with thermal profiling is your thermocouple attachment. That is Process Engineering 101. It's just like painting your house. The masking and prep work will make or break the end result. KIC did a DoE on which thermocouple attach

Hi. In the past years I had made dozens of PCBs but now I am trying to get a professional finishing on them. The main problem is oxidation of the copper traces. Basically I use the silkscreen method to make the pattern in both layers and then etch. L

I would suggest you do the following: get a sample / scrap board that you will be reflowing, attach thermocouples at various locations on the board, send the board to APS or whomever. Ask them to run a profile based on your solder pastes manufactur

I'm new to SMT. Now, i'm making program for SPI machine to inscpect for solder paste of SP60-MU. I think this is a very good printer but some times, my program shows only 50-60% of volume transfer; and the average height is very high: nearly 200 pct.

I recently witnessed a process in which the solder pot operator used Techspray WSOL water soluble masking to cover the areas around a connector that was to be soldered on the solder pot. He did not wait for the WSOL to cure. He soldered immediately.
