I've seen some plastic fingers advertised for wave solder machines. Anyone used 'em? They are 'glass-reinforeced polymer resin', they are supposed to stand the heat, can be mixed with titanium fingers on the machine, and cheaper! (near and dear to

Hello there We assemble Add-On cards for the Personal computers. Naturally all of them have gold plated edges to be connected into the pc. My question is : What is the best way to isolate these edges while soldering in the wave solder M/C. Hany

Gold finger connector over a wave solder, what would be the best way to protect the fingers from solder.This is a high volume job.

If the gold fingers are pad types which plug into expansion slot connectors, I have used a titanium guard attached to the wave conveyor over the solder pot, which allows the PCB to connect to the fingers but masks the solder from the gold pads along

Some PCB's manufacturers are now able to fill the hole and then re-metallized the pattern in order to obtain a final soldering surface perfectly flat but with an electrical connection under. This of course increase the price of the pcb but avoid any

I am looking for a vendor for solder spheres and tack flux for BGA reballing. Preferibly on the east coast or new england area. My current distributors have them but require a min purchase of 200,000 that's a lot of balls!!!! thanks greg

Although I am certainly no expert here I have seen a very fine looking piece of machinery for selective soldering. Although it too has a small fountain it is fully programmable and relatively fast. It is the Seho MWM3250. Check it out, it will be wor

We are in the process of researching and gathering information on establishing a zero-defect soldering program. I am sending for an IPC video on the subject. I am particularly interested in getting some direction and hearing from those of you in the

Via is normally a plated thru holes in (0.63 to 1.0 mm (0.025" to 0.040") diameter lands , which unless properly treated they must be located away from the component lands to prevent the solder migration off the component land during reflow soldering
