Techspray has a broad line of peelable solder masks. We use the Wondermask P for masking conformal coating as well. Call the company or rep to determine which product is best for you. I am not affiliated with Techspray in any way. If you get tired o

Have you heard about the stamp soldering solution for THT? With a 25 second tact time maximum, for any size board and regardless of the THT component count, and much better yields than a fine tuned SMT process, stamp soldering can remove the largest

I would choose wave over hand solder. Top side wetting due to thermal mass will be your biggest obstacle. Of course I don't know the size of your soldering irons or how weak your wave may be.....

It sounds like the process is very labor intensive, and all the verification is done after the parts are soldered. Assuming you are hand placing the components: 1 - Contact Systems semi-automatic placement machine. It show polarity when placing, so

| We are finding solder shorts under 1206 Components on the bottom side of our boards.In all cases these shorts are from either side of the component to a feed-thru under the component body. Adhesive is used to glue down the component and then the bo

After 16 years in the industry, I have honestly never heard of putting wax in a solder pot. Anyway, I do have some experience with Treiber wave solder machines, and as I recall, the air-driven pumps are a nightmare to service. First of all, make su

Hi Arnold, Some wave solder machines have a preheat function, that raises the board temperature before soldering. Some transformers use single use thermal fuses/TCO's inside, that trip at a set value (in a range approx. 70 degrees C to 180 degrees

Hi everyone: Our company is trying out immersion white tin for fine pitch assembly with what I would call mixed results. Reflow solder looks very good, but wave solder looks somewhat grainy (this may not be a problem in actuality). We had dewettin

| Folk's, | I'm in need of some help / direction. I'm working on my thesis for a masters based on looking at the effect's of the solder resist promoting / reducing the amount of solder ball's during wave. I'm looking at thing's like colour, texture,
