Assuming the following: L=Process Length of the oven t=Desired profile time in mins(depends on the paste/glue used) l=PCB length l1=gap between consecutive PCBs Then the total no. of PCBs per hour is" (L*60/t)/(l+l1) Vinit

Not sure how many inspections need to be done at 15 - 20sec total per board, but you may need to install multiple SPIs/AOIs to hit your takt time. Mike

It may be worth mentioning to those that do not have the ability to rotate the PCB, that some folks adjust their aperture design on fine pitch leads by increasing the aperture size for those leads parallel to the X axis, thus allowing consistent volu

Wow, you're using the Surface Mount Adhesive for mechanical vibration? I've never heard of SMT adhesive being used for things other than holding the components in place before wave solder. Does it work for mechanical purposes? Glue/Wave is a proce

At 250K / month, you may need a few Mydatas. They are great machines but not all that fast. Bottom line, without a BOM, size board or panel size, no one in their right mind can tell you what machine to go with. They can tell you what they like, bu
