Hi PPM! Have your stencil house mark fid with laser machine - that how we use to have fid mark once it marked with laser it last very long time like stencil's life. Good luck! Steve USA STENCILS INC

The Tant size is 3528-21. I use type 72 nozzle > for it. check your vacuum valve, manually turn it on and off,i have the same problem like that b-4, after replacing the vacuum valve, the problem went away.

Remember as well, the Mirtec machines have laser technology being used to check for coplanarity/lifted lead issues. Having this capability will reduce false calls in most circumstances.

Hello, We have a DEK 265 we will run our boards front justified with relation to the stencil, can anybody give me an offset that you are using to order your stencil when the image is in the front? Thanks

See attachment. Hope it is useful. DucHoang, Thanks for the info. This is exactly what I was loking for, since I didn't have a DEK manual with me. Thanks a lot!

I use Center Edge, and adjust stencil offset. It's very easy, you just have to give it the PCBs width. An other advantage is that If your PCB has scrap strips, and you lose them, or PCB changes, you can print it anyway.

Instead of using a conversion box just make your own cable. Look in the Dek manual, volume #2, chapter 18. It shows you how it's wired. Easy to make and looks allot cleaner than those conversion boxes.

Is it possible that the assembler is using solder wire that's too small for the application and feeding it too quickly to compensate?

Possibly, if you want to sell used equipment you should have a competent technical staff! Jerry

Don't know about Topaz, but on Essemtec machine using SMC ejector, there are separate solenoid valves for vacuum and release. The connectors are identical and side by side. If these connectors were swapped then I would have the symptoms you describe.
