Hi, from what you are saying I am not sure you need turret head. One operator means you will prefer a machine that has feeders on the front only. Remember that the machine speed has nothing to do with the number of boards you are going to produce. R

Like I stated before, I am not familiar with the machine. I can only make suggestions. If you found solder paste on the nozzle, clean it off to prevent part stuck to the nozzle tip. I would also check if the nozzle tips are being worn off; uneven we

Hello SMTA, We have some flex board assemblies that will require conformal coating. Coating rigid boards is nothing new, but this will be our first with flex. Are there any challenges associated with coating flex PCBs? on this particular assembly

Hi, I have a general question about the relationship of PCB thickness and BLR testing result. For example, I have QFN6x6 parts mounted on board in 1.2mm, 1.6mm, and 2.4mm thickness. All boards have 6 layers of Cu. Studies show thicker board gives les

Consider an adjustable (or fixed) process carrier then. It could offset the board so that your component is better centered. I have used Pentagon EMS for such carriers in the past. They are pricey, but last forever. We were a contract house, so the c

How can I upload image to this forum? I can show you the pad layout. I am thinking maybe too much solder. I used 0.16mm thick stencil but notice many us 0.12mm thickness. Also, cream layer is 100% of pad surface, I know for fine pitch parts it is r

Thanks, I'll take a look. Something else I found was the Z height for the module was set to 1.7mm but I am picking up the part on the PCB surface which is only 1.0mm from PCB being loaded, therefore the part must have been let got 0.7mm above PCB an

I suggest you buy 8 zone oven, its best for baking and you can easily control overflow of heat, I am also using this, I recently bought it from https://www.reecoupons.com/categories/black-friday and I easily can control heat whether its overflow or n

Hey all, i'm hoping to get some feedback from the community on baking process versus a dry box. current process we have for rework of PCBs is to perform a 16 hour bake cycle on hardware before BGA rework is performed. however this process is ineffi
