We have experienced contamination under flat chip arrays. The lab report is still open but it appears to be dendrite growth. We have been trouble-shooting our process and cleaning equipment. My question is are there any specific design or best p

I am new to flex circuit manufacturing, placing SMT. We have a need to use this technology, but I have no experience in the process. The sample our design engineers have obtained are from a company called Allflex. How does this process work? printi

I have one product which only need print low temperature solder paste on OSP pad. This pad will used for hot bar process. Desired solder paste thickness is 0.10 mm to 0.15 mm. Is any one can advise right stencil thickness and aperture opening for it.

I have the following questions with regards to the solder printing stencil design : 1) Is the Electro-polish process recommended for laser cut stencil ? 2) Should the aperture walls be slanted at an angle or straight wall, i.e. trapezoidal openin

"Although some lead-free pastes performed adequately and newer pastes work better than earlier formulations, this detailed experiment confirmed that tin/lead solder pastes wet back to PCB pads better than lead-free solder pastes. Therefore, a more ac

Boy, I step out for a bit and everybody picks on me (just joking). I believe I may have been off base a bit. Checking every bit of your stencil design is very good - I do that too. I calculate LXWXH and reduce or over print where needed, depending

Many beginners do not know how to start learning hardware circuits. In fact, the "hardware circuit" is composed of a part of the "unit module circuit". The so-called "unit module circuit" includes: various regulated power supply circuits (like the LM
