Ask A Question


I can answer questions about electronic devices' development processes, PCB design and manufacturing processes, Assembly processes and anything related to electronic products engineering. I do not provide schematic designs or any other designs for free. I can, however, give advice on the validity of new designs.I'll not answer questions regarding fixing electronic products/devices or draw schematics for you! I can and will help you fix your processes. Electronic product engineering IS NOT electronic engineering!

Experience in the area

I have more than 20 years experience in electronic products engineering.Anything and everything from design through manufacturing to maintenance.

What do you like about this subject?

Product engineering is like playing multi-dimensional "Lego". Each tiny block must be fit in to its place at the right time. Paying attention to details is important and time schedules can be stressing but the game IS FUN (and you get payed for playing it successfuly)!

Something controversial or provocative about this subject

Product engineering is part of the Product Lifecycle Management - PLM - which is a hot subject in both electronics and management worlds. Remember! No PLM is complete without marketing!
