"Any risks associated with double pass stencil printing?" Mostly just too much paste, plus the associated bridging, and your stencil gets dirty quickly. Any gap between the stencil and the board gets filled with paste on the first pass, then migrate

The APE machines are still OK in their place. We still have two APE machines that are over 8 years old and still are good for some processes, but have been consigned to the leaded solder rework area. We have upgraded to AirVac since the advent of le

I must ask the silly question- are you sure you deposited the correct amount of paste? Depending on aperature design-the voiding could come from a stencil that has its holes partially built up with old paste. If paste volume is guaranteed, then what

Has anyone ever used local fids on flex circuits that are applied by the board house as black ink dots? Good or bad experience? We have a flex board that has two identical 60 pin, fine pitch connectors on it. From limited experience and reading so

We have this machine. It is a dream when it is working. We purchased from a larger company in town. Their in house service guy was servicing it for us whenever we could get a hold of him. There is an issue with the camera track. High pitched wining/

That AP can paste 0201's and has built in 2D. I would keep it. The AP series "forcers and platens" design is a bit fragile, but reliable and tends to last a long time. My biggest complaint is the cheap air hoses to the 3 forcers. After about 8 ye

If I read you right the issue is mostly with components from one supplier. I'd suggest looking at the components under a microscope. Also, if you have some old pre-tombstoning parts from this same vendor take close-ups of both and compare them side

Last year I had my doctor do a lead test during one of my regular blood tests. My exposure at work is similar to most of you, I'm sure. I've been doing this for 13 years now. We do predominantly leaded solder processing through SMT and wave. I wash m

Hi Base, I guess your right - due to the complexity of the software we plan on keeping the source code under our control BUT we will not be dongling or protecting it in any other way and we will be publishing the program on our website. We will pub

Hi all, I have a OK industries hot air pencil model number SMT-1160 even though the label on the base says its a SMT-1102. The problem that I have is that the Diaphragm (diafram) has ruptured inside the small internal air pump. Where can I get a p
