Whatever, we process the cover tape to troubleshoot the provlem.

We can use cover tape to solve, SMT throwing rate can be reduced to less than 3%.

Hi, We are facing the issue with Component orientation(Wrong orientation), during Proto build/NPI time in SMT for 1st board placement. We are not doing 1st board with STICKY board, directly placing the components with Paste board only. Pls suggest, H

you can check several things here: 1.Is this original tape or it is tape and reel service? 2. Is the cover tape that sticky, to lift component a little bit(sometimes might get the hole component). 3. Hole too loose, allow it to move too much 4. Fee

We appreciate your desire to find the most time effective method of reworking these boards. However, we believe that your most efficient method will be to have one assembler remove all of the parts, and a second assembler place/hand solder the parts

If you mention mis-alignment and missing component in the same sentance, I suspect the component is not properly released after placement. Assuming the Juki machines use an air blow, after vacuum shut off, than I would look at a correct air flow firs

Does this only happen with certain feeders or certain components? We have a few regularly used components that experience the same problem ( Philips SMT machinery ) where the cover tape is just too sticky. Experience taught us which components will c

Hi, Bob you're right. I replaced the Z-rod and the machine started to go alright. When I examined the head's mechanism I omitted to check the most exposed an delicate part... my bad. The old Z-rod came with the machine, and its slide movement was loc
