Without being clear on whether you're talking about: * Standard air knives at the back-end of your in-line cleaner ... OR * Hand held or similar nozzle. Standard air knives: This causes no problem with ESD because the relative humidity is so high t

I am in the process of making a requirements-document for manufacturing of a PCB. I would like to state some requirements for maximum allowable component shifting in the final PCB (both displacement and rotation). However, I can't find any (IPC) sta

Hi all, Does anyone know of a software that will import a standard gerber, load the layers and highlight the tracks so point to point testing of can be carried out to debug a PCB? This is something that i saw used some years ago, but i have not bee

We have had the same problem with several boards, and the problem was with the land pattern design on the PCB, not the stencil. We found that the part tends to center itself on the one large pad, and if the two smaller pads are not the right distance

Mark, I am having difficulty picturing exactly what you are doing, but I hope this helps. We occasionally use jigs through SMT, usually because the board is too small/thin to fit the smallest rail width. In such situations, we normally make the jig

The current IPC/JEDEC standard J-STD-033 for moisture-sensitive devices does not include a bake cycle at 90C (it includes cycles at 40C and 125C for non-assembled components in reels or trays). However, the upcoming revision, which should be release

My software can easily open a PCB CSV file so this is probably the easiest way for you to generate a file. The setups are remembered via a write to the registry, so you can go with a standard set of values to arrive at a very usable file without havi

Hello, I want to ask on suitable temperature profile for PCBs with ENIG final surface finish. I know that it is complex question with many unknowns. When the PCB will be standard 1,5 mm 35/35 Cu and the amount of components will have any influence o

The Mydata machine's Y-axis moving does not affect parts already placed on the board. The machine has very sophisticated acceleration and deceleration to account for this. There are many users of Mydata machines running 0.3mm pitch and large heavy pa
