How are your experiences with stencilling 0201 components on large circuit boards, i.e. 400 * 250 mm ? Will there not be too much mismatch between between stencil and (FR4) boards? If so, would dispensing be a solution? Any other solutions?

Hi everybody. I need to calculate the moment of inertia of a pcb (with its components) and also its center of mass. The pcb is not manufactured yet. Before that I need to verify those properties. How could I do? The pcb will weight around 50 g. Shou

Sn corrosion effects were studied for stainless steels, coated stainless steels, titanium, cast iron, and other materials. This study can be found in the SMT Library under "Equipment Impacts of Lead-Free Soldering" Electrovert uses a Melonite coating

Doesn't sound like we use it exactly like your application. Similar to what davef says we use it for smaller to medium size or dense parts (sigle dot under the center of the part) that have potential to fall off on 2nd side processing. I can say it

In BIG-boy, high vibration applications to secure large components, we've used 3M #2214 structural adhesive [One part, 250*F (121*C) curing 100% solids, paste consistency epoxy adhesives designed for bonding metals and many high temperature plastics

We love Loctite 3609 as a chip bonder, but would never consider it to secure large components

I am attempting to identify a good epoxy to hold on larger parts on thru the reflow process for the opposite side. We currently dispense epoxy prior to second reflow on the corners of the component because the epoxy we use cures before reflow and doe

hello everybody , i am looking for the elementary caution you need to take when you reflow large board with several thousands of smt components . thank you for your advise
