Depending on how you frame the question, either of you could be correct. Neither of you mentioned stencil thickness, which together with aperture opening [and stencil fabrication technology] define how well a paste will release. So, the key measure

VG foils are about 5mm thick and two in the rack takes up just under 20mm, so admittedly not a ton of space savings. That's not the only reason I like the VG system though. It takes multiple failure points (screen tension/mesh adhesion) and reduces

| i am trying to design a stencil fixture for manual printing. has anyone done this before or has an idea? thanks | There are sooo many variables; product size, 1 vs. 2 sided boards, support, component size, pitch, stencil alignment, PCB thickness,

| Has anyone used the mechanical stencil foil tensioning system from certain company that eliminates using stencil frames and epoxy & mesh? Any comments on whether it's worth looking into? We go through product revisions like we go through clean so

You will need to set the contact and squeegee zero calibration every time you set up a new product, we do this because the thickness of the substrate (pcb) can change between product and this will effect these calibration settings. The machine does n

We assume by "stencil tension" you mean a measurement of how securely [or how tauntly] the stencil foil is held in the stencil frame. If so, we do not know how you would go about making your "30 ~ 50 N/cm" limit measurement when verifying conformanc

Dear All, I have OSP finsh pcb on my production, the pcb thickness is 1.5mm and the product is one sideded pcba. After reflow process, Is there any specific time frame defined for smt completed OSP finish pcba before going for wave soldering proce

Can you use the equipment manual as the basis for learning how to use the machine? Each model of printer has different alignment techniques. We don't have a clue of your model type. So, we'll approach the question from its most basic point. Registe
