We machine place the first part, then add two dots of dispensable solder paste to the top of the terminations, then hand place the second part on top of the first. Reflow. It works better than hand soldering after reflow. The solder paste is dispens

We recently bought a Scanspection machine second hand but there seems to be a problem with the PC side of things. AOI Systems have not been helpful at all and won't support the machine. Does someone have any experience with this machine or can give

We often do double sided SMT assembly, never had issues with smaller components. However, we apply glue to heavier components like inductors, SD card sockets etc. For this purpose, we have a glue dispensing machine inline after the solder paste prin

Yep, checked the nozzle (that was my first port of call). Had a look at it under our microscope, and also swapped it out for another nozzle to be sure. The problem still exists. You can set the theta speed, but only to Fast, Medium or Slow. I've

Thanks so much for the reply. I had looked at Juki but must have missed that model. I see what you are saying about the dispensing. I was looking at the Mycronic solder jet system the My700 I believe. I have watched a few videos detailing the pros an

Hello Diego, are the components missing on the first side or the second side. Like Mr. Evtimov said, you can check before the oven the pcbs's visually and see what happens after the oven. In this way you can see if it is the oven for sure. Then there

YES to the first question in some points of the board. Bulky, to the second question when it is not in short. What you say about the PAD height, helped me to understand why the SPI shows weird values for other measurements. I am currently doing test

I have a small 5mmx5mm 32 pin QFN I need to program and want to find a way to do it automatically. Companies like Xeltek charge $100,000 for an automated programmer and I think it can be done with a regular pick and place machine by placing QFN into
