Hello, We are using a film piezo electric sensor to deduct and measure vibrations. A long twisted pair shielded cable is used to connect the sensor to the signal conditioning unit (the signal conditioning unit has to be kept at a distance from the se

I wouldn't raise the temps just slow the conveyor, You need to get the PCB "soaked in". It seems as if you are applying more thermal energy than the PCB can accept in all areas. Does this oven have convection heating? Hopefully so. I have found t

Glad to hear a little success from ya Duckmann! i have stenciled mask in the past and I can tell you that stencils are expensive. They are basically a step stencil, you will need full thickness for the area(s) you are going to apply mask and you wi

Mrduckmann2000: Why do you want to do this? * Removing a non-washable / peelable temporary solder resist [TSR] is going become very tedious, because they do not release well from small / tight / isolated features. * Clay from washable resists will

Davef, You have a good question. If we had perfect design engineers out there that would use the proper component spacing and not put SMT parts between and around thru-hole parts - glue and wave would work perfectly. I have done this with great su

Pete, I was speaking to the Electrovert/Speedline/Camalot/Gemini factory tech's and App Eng's. I now have new machine files which slowed the pumps down to half speed, I have several needles....all of which still will not place a small enough dot.

Cellular and PDA architectures employ this technology all the time. You have to be careful with your board supplier as well as with your plugging approach. Leave the via unplugged, I guarantee voids in the solder joint. That leaves us with, "how d

A couple of things.. 1) The problem is more than likely on the magazine board itself (TC2), most likely the pal chip that stores the serial number and feeder information (you could swap this with a working magazine to verify) 2) The magazine connecto

Ken, You nailed it! We have a Electrovert Vectra wave solder machine that will erupt solder all over the place while heating up, we had to disable the timer because of all the solder splatering. Electrovert told us that our machine had a small des

Hi does anyone have any experience of running Sn 99 Cu0.7 Ag 0.3 solder in their waves? Also is there any reliabilty data available? I think it may also be called C7A3. All I can find is a brief mention in a table in IEC 61190-1-3 2004, and on a pr
