Hello everyone. I'm looking for some general information on reel counters. We are trying to tighten our inventory counts, and rather than estimate a reel we're looking into getting an accurate count via a reel counter. So first, I'm wondering what

Hello Sir. We also have faced a same problem. At that time, we had to repair it because we could not find any solution. But in our experience, the void underneath FET was more severe whenever we used the FET that have been made long time ago. It is

Manjunath, I prefer orthogonal systems. In my experience they are actually better at detecting coplanarity and HIP defects than multi camera systems. They are obviously limited, in that they can not inspect a component under another component, b

Sounds like you and your board suppliers have done alot of work with this issue trying to solve the problem. When I got into this situation previously, I relied on an outside lab to help me. We didn't have SEM or any testing capability at my shop eit

I always fix thermocouples to pcb pads across its width. Then rotate it 180 degrees to check readings. If I am happy that the oven is giving results within a few degrees C then I'll crack on and set up a soldering profile. I am not sure what the oven

We do a similar part on a Fuji IP3. Set table speed to low. I do not know the QP, but if it's similar to the IP make sure the board clamp/unclamp is smooth. On our IP it got dirty and was jerking causing the board to jump a little which bounced ou

I just got word from my board designer that the actual pad size is 11.8 mil and he is reducing the paste layer to 7.8 mil. To me this is way to much of a reduction. I am was accustomed to doing 20% reduction on any thing 20mil pitch or less. The scre

Our employees use a knit style ESD glove when masking boards to prevent oils. They snag alot and bend leads and cause other problems. I have tried dipped palm but they are bulky and dont offer "feel". I tried a silky type but they had a huge seam
