Conductive Anodonic Filament My worry is that any extra moisture added to the Lead free Material during assembly may cause this Conductive filament to grow within the material weave. They are water washing after through hole assembly and then after

What solder are you talking about and what reflow method are you using? High Melt Alloys: SN96 (Sn96/Ag4 or Sn96.5/Ag3.5) - Simliar to SAC305 although normally uses Rosin based flux that can required more extensive cleaning. Pb85 (Pb85/Sb10/Sn5) -

We recently got a job where (after placing SMT parts) we have to solder LED dot-matrix 8x8 display modules manually on the pcb. Due to the PCB design, it has to be TH type (also, it's the only type available) and soldered manually (or using selective

Sorry I have never worked on the csm's you can get an old topaz for nearly nothing. Those are easy to calibrate. What could be an option is to place an X-row of chips under 0 degrees 4X then 90degr 4X then 180degr 4X then 270 degr 4X. Place them al

I'm in St. Louis, MO, US Midwest. I wrote my own CAm interface, and it works REALLY well. It is only about 2 pages of c code. Of course, it only translates from one CAD package's format to one P&P machine's format. That makes it much simpler to w

We have a DEK 265 also. It may be the PNOZ (relays in a box) or the "in rush" capacitors "leaking" or "opening" causing your power supply symptoms. Went through something that sounds similar to your description of "power supply" problems. Your best o

Yes, it's powered up. We use a simple power supply that connects directly to the drive. It spins up fine. I belive my problem is with Windows not recognizing the old type of drive correctly. It does recognize it as a mass storage device (the drivers

SR1000 is commonly used for tenting. Search the fine SMTnet Archives on : tenting Someone gave us this note. We have lost their name. It seems to be good advice. If Liquid Photo Image (LPI) solder mask is required, do not tent via holes. Tenting

If you are in the US/Canada contact your local Juki distributor and talk with them about this. In ancient history times, I had 570s and upgraded to their newer machines many years ago. At that time they had something that would convert the 570 plac

basically the rule of thumb for the 8mm feeder is that you only want one component exposed in the pocket at a time. If you see more than one component exposed you need to go down in size. The reason for this is that if there is another component expo
