Questions you would ask if someone said they had a 3D printer for professional multi-layer PCBs?

Firstly thank you for your time and consideration. Yes a professional device along the lines of the products seen on kickstarter. A system to be used by labs, R&D, product development centers etc. The difference from current offerings being resistivi

To get real conductivity in your traces you will need to remelt your copper or silver tracks. This means 850oC. The other method is plating at low temps, or etching. Epoxies like all carbon based compounds vaporize at 400oC. Next problem epoxy fibre

...Unless you could dispense a fine glassfibre mesh in much the same way a 3D printer extrudes plastic filament and then spray epoxy over the top. It would be remiss to 2nd guess what compounds physical chemists can come up with for such a project. E

When I and some friends worked on this project we were aiming for an hour turnaround time. But as the years of development went on we upped the board specification considerably. Also the world changed under out feet as we could get commercial protot

Thanks Sarason, You are right that chemists and physicists now have some new tricks. Using nano-chemistry the physical properties of the materials change. The melting temperature of our nano-particle silver is below 150C. The insulator is also a nano

MPM UP2000 Squeegee Problem

Thanks for the answers guys. I knew it had something to do with the calibration menus. It had just been so long since I had to do maintenance to an MPM printer. I had been working with DEKs and Ekras for the past 6 years.

It would have to be really CHEAP! I ran one a few years ago, had 3 4C's gained together. Always had problem with the software and it was a high maintenance machine. Never had such problems with Mydata, Phillips or Zevatech. Also, it seemed I alwa

We also use the PPC-N29TP in both of our facilities. We've had both for over 6 years. Both have had some issues ie: new touch screen and our other facility has had leaking issues, had to replace seal for tank. With that being said, overall happy w

I have had both DEK and MPM. I have had far better success with the DEK's. They are far more reliable, require less maintainence and are on-line more than any of the MPM's I have had. I have only DEK's on my lines now.

BGA rework: Coplanarity of Xilinx before and after reflow.

I have had the same problem with this supplier, we found that one mfg. place or process used a .015" piece of FR4 as the base while others had .030" Fr4, We discontinued use of the .015" and never had a problem again.
