Hi Thomas, Thank you for your posting and I agree with you that Printing is the most difficult one. BTW, after you ran the one side (let's say Bottom side), my engineer worries about the distortion of flex board because of the thickness. In that ca

If your frame size is 730mm x 730mm then you can't move it left or right. If it smaller than that then the frame adapter will give you more leeway. I am not too sure by what you mean by "If I had a 6" board, and a stencil with cut-outs for both side

Hello gurus, I am a hardware designer with a small company. We are about to send a new PCB for fabrication. This board uses dozens of tiny QFN, DFN, and similar packages. As a final check I have been going through the datasheets of all these parts t

I checked the spec sheet and it gives pressure and no volume. The volume on one of my older Yamaha's was about 2.7 CFM. That corresponds roughly to the volume of a small 2HP compressor at your local hardware store. You can place on of these in a smal

It's been awhile, but, some other things you might look at: - Check the fiducials on the toolbox. If they're getting obscured/damaged, all kinds of weird things can happen. I had problems initializing tools one time because of this, and I could actu

most, possibly all of our clients, don't specify this kind of thing even when they are in fields where you might expect they should and should be aware of them. However if you cherry pick a couple of class 2 requirements such as offset and joint widt

Hi! What exatly you do? Do you reflow the both sides of the board at the same time or you reflow your second side? I think in both cases you should decrease you bottom zones. If you reflow both sides - with 10-20C(F) If you reflow the second side - w

I am looking at buying a pick and place machine to assemble the circuit boards we make. Most of the boards are small (2 to 10 square inches), most are 2 sided, and have maybe 20-50 parts per side. I use mostly 0805/0603 chips, SOT-23, SOD-123, SOIC

I was wanting to know if double sided reflow can be done with a metal plated BGA on topside. We would be running bottom side first. My boss seems to think the only way it can be done is by placing glue dots on the bottomside compoents because the B
