Dreamsniper, We would need much more details about your process to help you to determine the source of voids. Type of paste, how long you leave your paste on stencil, your relative humidity, reflow profile, type of oven, oven environment (N2?) and so

for backward compatibility applications (such as this), the higher melting temperature alloy (LF alloy) gets the priority in selecting the reflow profile. you are using too low temps for reflow. your LF alloy wont reflow at these temp and you will e

Craig - You should not use the leaded parts, as you are, in all likelyhood, going to see massive voiding. We just went through this same deal where I work, because a manufacturer sent us the incorrect parts. You can go with lead free parts with regul

Be careful and review the MSDS sheets on any dross inhibitor reducer etc. Most are extremely hazardous. We offer a product that is not hazardous it melts at pot temp. forms an oily substrate, removes the good solder from the dross. Also can be used a

Thanks for your advice. My business model is fine, but I just find it to be unreasonable that there isn't a "no frills" oven below $3500 that maintains quality. I'll spend that much if I have to as I don't want to mess around with bad solder joints o

We are using Kester 985M in our Pillarhouse Jade. We only run SnPb, but this is a newer formulation of flux that is suitable for both lead and lead free alloys. Call the manufacturer of your selective soldering machine and get their advice. They ty

I am looking for used fume extractors. The type I am looking for would be a floor model that would support 4 soldering stations. We currently have some Impell Filtermates. So something similar to these would be ideal. Does anybody know of a compan

Years ago I received a sample of adhesive dots that were on tape and reel and could be pick n placed with standard equipment and withstood reflow. I have a current need for these and cannot remember a vendor or manufacturer. Does anyone know of this

Simulating with what? In developed countries manual labour is expensive but is also still the most common solution to fitting though hole parts, even if the board are then wave-soldered. Mixing SMT and THT on what sounds like a very simple product wi

Resources are: * IPC-7525A - Stencil Design Guidelines, 3.5.2 Step-Up Stencil This type stencil is useful when it is desirable to print thicker solder paste in a small portion of the stencil. An example would be a ceramic BGA where it is necessary t
