Hi all, 2 weeks ago we installing a new P&P machine - chip shooter.But , after installation proved that vibration of the new P&P arе very strong.If I use mashine to 100% of the speed the machine vibrating and after 2-3 panels moving 3-5 mm.The machin

We are designing board which have to plug in M.2 connector and thickness is limited to 0.8 mm The board is very complex with many BGAs and DDR3 memory chips and we will need 6 layers for routing. The problem is that we will need signals with 50, 90

They're open ended on the thickness (read that as, have no clue). They've indicated that they would like the coating to protect the circuitry from ESD, and mechanical shock. They also would like to be able to see the LED's through the material. An

Which is the best way to clean the PCB after soldering? Is it good enough with IPA (isopropyl) or with the Flux Remover spray? However, we use a lead free solder wire (3,5% flux inside the core) and after the soldering its a visible wet and surface g

Hi! I have a very basic question about PCB cleaning. Which is the best way to clean the PCB after soldering? We use a lead free solder wire (3,5% flux inside the core) and after the soldering its a visible wetting,flux around the joint. When using th

The problem is registration between the stencil & the smallest pads on the 5 substrates. Using SPI s/w I can overlay the paste layer over the PCB image to determine stretch/shrink. Our worst case was shrinkage of 10.2mil on a 5-up 300mm panel - small

Keep some empty tape and splice a long enough piece onto the foot of the tape to keep the strip and the reel connected.(Brass shim type splice being the most reliable) Or Print 3.5mm labels (Brother PTouch make one this size) and stick those onto y

we have a Cyberoptics Flex ultra HR machine (model N 8010949). the alignment of camera 1,3,5 and 2,4 is impossible because the images from each Fire wire adapter don't have the same size. we tried to calibrate with the target board, but also unsucce

Hi, We are facing a complete new package type for us in our prototype production. RoHS LGA 36 Land Grid Array with 36 so called pads instead of bumps underneath. It is totatlly flat. This component is only 6.5 x 3.5 x 1.6 mm and we recieved them in a
