Hi!!! I think, you should visit www.enthone.com this it's the internet place of an inks company named Polyclad Technologies. I hope this information can help you...

Permanent Marking Ink for ID# on PCB while circuit board is being built on Flowline

Electronics Forum | Mon Jul 03 14:47:35 EDT 2000 | Ashok Dhawan

In a typical flowline assembly of circuit boards, what are the different methods used for tracking WIP ? I can think of : 1. travel cards - not suitable for panelised boards 2. Marking ID# on board at various operations while board is being built.

Ashok- Rather than ink, consider using a paint marker. This is much more permanent (not easily removed with alcohol), is easily applied, comes in a "pen" like magic markers. Many pen tips available and a large choice of colors too. The down side is

You ought to consider Data Matrix directly marked on the boards It can be done with laser, inkjet, or other permanent marking methods. Never falls off, can be read even if 30% is obliterated. For an example, check any AMD (K6, K7) or Intel Pentium c

How can i simulate vhdl code or graph in analog circuit simulato

Hi, you can do it using Cadence and it's subprograms or you could find someone with ownmade convertor(there are a lot of people who work om the problem last years.I know 2-3 and if I find some of them I'll give you their coordinates.

Hi Benny, Move on over to some other forum like EDN or EETimes and piles more to post your question. Your luck will be vastly improved. This forum is not the best for electronic design issues like you are asking. YiENG, MA/NY DDave

Is it possible to get gerber design of PC RAM circuit boards?

We'd be amazed if anyone gave your their board layout for DDR3 bare board. * Design is very complicated rambus.com/assets/documents/110131_designcon_lu.pdf * Further, the layout requires a significant effort youtube.com/watch?v=FbfBKqtIkGA Don't gi

Seeking a "Unit Test" circuit board for testing a Pick & Place

I ended up just making a new test board as we had some specific PnP abilities we wanted to test, but I did follow up on your link and got a quote. The dummy components were way cheaper than what we bought from Digikey or what I saw on Topline. This w

Ashok: You're still goin' down that ol' ESD road aren't ya bud? Why do you need the boards to be dry? Conformal coating? Hey wait a minute, are you one of those no-clean people? Er zis related to the Kapton tape res fandango? Anywho, be careful

Ashok: You still didn�t tell me why you want additional drying of your boards, but what the hey, we all have our dark secrets. Anywho, let�s consider some options for reducing the moisture of your cleaned boards: OPTION 1 - Up-Grading Your Cleaner
