Vlad, Reduce your aperture opening in the stencil, this will give the stencil a good seal around the specific area of concern. In a wave solder environment, solder balling top or bottom surfaces in a wave pallet is caused by excessive flux burning o

The UL Safety Laboratory is the most authoritative in the United States and a large private institution engaged in safety testing and identification. The UL+ number on the PCB mainly represents the UL certification of the circuit board in the United

Rob, you can always create a program and inspect the paste with your Checkplot. If you want to take it further though, you will need a centroid file. With centroid file you can lock pads to belong to a reference designator. When you do so you will n

Hi, Rob. I have used Parmi and Koh Young SPI. Both have epmSPI software in which you load stencil gerber, load cad data(if you want) connect the pads to the designators, point fiducials and done. Can take from 10-15 up to 30 minutes, depending on how

A few times I have had success limiting movement in the oven by splitting up the paste apertures. In this case it might work if you had three bricks perpendicular to the leads.(maybe more) The trick would be making the gap between them big enough to

If I understand customer's intention correctly, it would be fastest, mass production with fully utilizing the Pick-N-Place machine capacity with minimum manual labor which won't break the bank. They used to manual hand soldering the coil to the boar

Yourself , well you can test whatever attributes the devices should have to see if they align with the specification. You can inspect the packaging and markings to see that they match those of the manufacturer. You can also check if the parts have va

Personally I like #1! Being generic isnt always a bad thing. Many times I have come across concepts, products, and ideas that I would not have found had I not been searching through a "greater/broader scope" of topics and subjects. Organization is

I had a similar problem once on an acculfex. The root cause was a short on the one the wire harnesses connected to the print head. If I recall, most of the relays in an accuflex are actuated by the 24 volt bus, so if you have a short anywhere in tha

Most PCB Assembly Houses offers free wide-range DFA before the production run to ensure the design is capable for manufacturing. Actually, for pcb designers, it's recommended to be aware of the concepts of Design for Manufacture and Assembly of PCBs
