We print on plastic film using flexographic, inkjet, and gravure. We want to print simple transistors as components in a simple oscillator circuit. The transistors can be relatively large size, do not have to be transparent, and do not need to be high performance devices. The circuit is a simple blinker, turning a pixel "on" and "off" every half second or so, and actually at 32-44Hz. The current is only about 20uA, voltage about 4.5V-6.0V. We need you to guide us about printed transistors. We are familar with printing silver nanoparticle inks, PEDOT inks, and ink formulation. We are particularly crafty at formulating PEDOT based conductive adhesives. We are also capable synthesists. We need you to suggest commercially feasible chemicals. We need you to suggest water, solvent, and uv coating formulations. We need you to suggest printing techniques. When synthesizing, we need you to guide us to safe materials, with affordable waste disposal. Many suitable chemicals are available from Aldrich : [login to view URL] [login to view URL] In your reply, please offer a few words which indicate the optimum materials and technique to manufacture transistors. Thank you for reading this job posting and for your support. Allen Engel.

Hi there, I am a rohs/reach/conflict minerals/components analysis engineer by profession. I can do bom scrub to find out the rohs, reach, eol and obsolescence status of components in bill of material. I won different analysis tools, like ohs 4d-online, silicon expert and part bom review. I am good at finding FFF-cross parts for hard to find components, EOL, NRND and non-rohs parts. MPN, description cleaning. I can do part validation and analysis. Please let me know if you have such requirements relating to component level,

Greetings! I have a PhD in Physical Chemistry and substantial experience in R&D. Regarding the manufacture of transistors- Silicon is the base material generally used, you will also need other materials for doping(P/B), etching(acids) etc. Processing steps involve lithography/masking, deposition, etching. Let me know if you would like to discuss further!
