We do our work instructions manually..... taking pictures of actual parts and process. But I have this idea of converting the conventional printed WI's to video instructions. I am now proposing a flat screen per work stations and video will play on e

Skill and experiance level of assemblers is critical. High skill and experiance with the type of assembly, print and BOM and hgihlighters. Day labor would be 5 to 10 components for each assembler, already prepped with pictures or drawings showing wh

Clint, You may want to call KJ Marketing Services, a Canadian company that fabricates plastic laser cut stencil. They call it "Kepoch stencil" This material was originally developed by Dupont, and patented and marketed by KJ. It was available for

I worked on MicroFlex. All axis move via electric motor drive. Carraige reapatability is +/- 0.0005" (12 micron). Cameras position more easily on linear bearings than the swivel type. The alignment accuracy and repeatability easily supports sub-20mil

The MicroFlex is not really new. Its the UltraPrint 100 re-engineered and improved. UltraPrint 100 / SMTech 100 has been around for many years. I don't believe the DEK 248 offers a Stencil Wiper option. I worked on MicroFlex machines. Vision system i

You should be able to get a one-print Mylar frame for the SMTech 90 machine from SigmaPrint, http://www.sigmaprint.co.uk Yes, with vision you store images of two features such as solder lands or fidicial marks from opposite corners of the board. With

We use Thermoset MA-420 on a pair of Elite 6920 printers. Excellent results. It took some experimentation with aperture sizes and stencil thickness but it works great.

Anybody have any ideas on the proper way to screen solder mask onto a PCB? I am going to cover SMT parts that were soldered to the btm side of the PCB, now I have to mask them in order to run this animal through the wave solder process. I know it w
