Hi, This discussion is really getting long. Fuji and other high speed mounter is great and better than small flexible mounter when it comes to speed.But, I rather suggest a modular mounter specially for subcon companies. Let say we combined 2 or 3 m

J-STD-001C just requires that the area not be so dirty as to contaminate your product, tools, workspace, etc. If you start counting particles, you're into cleanroom territory. Do a search on ISO 14644-1 for specifics. Actually Wikipedia does a ni

Hi, I am experience problems while testing wave soldering SMT components that are glued on the solderside (lead free). Between de leads of SOx type IC's and SOT's develop a great deal of solder beads. I have been using a RSS temp.profile while spr

You have a lot to think about! What does the flux manufacturer recommend as far as specifics like water temp or pressure? Do they recommend high temp di-water a detergent or saponifier? Do you currently have a cleaning machine, batch cleaner or inl

we worked out that the wave soldering cassettes Duratstone material takes alomst 35 degree away from the surface of the pcb, and the speed is already too slow it should be over 1.0 - 1.8 meters a minute but its now already 82 cm a minute, in order to

I forgot to mention the mass placement machine from Nitto. The Nitto machine places all components out of bulkfeeders. Plastic tubes are routed above the feeders pick position and into cavities of a template. The template is made for the pattern of t

Well gasketing yes, have you dine enough analysis to blame aperture design- Maybe not? Maybe whip out the gerber files for this PCB&stencil and compare the details with one you feel works well. Is there something different about their layout rules o

As a CM, we don’t have a lot of input on the PCB layouts we receive. Some engineers/software packages output the paste layer 1 to 1, some do an across the board reduction, and some set each part up individually with different reductions per footprin
