Also I should mention, I've ditched the formulas for getting the "optimal" solder amount after being bit by them once. Now I just design a PCB with 4-10 spots for the connector then order a stencil with a range of aperture sizes. Figure out what give

I am not sure that is doable. Ground Aperture is very small(for the stencil blade to get in there) and very close to the other apertures. I want to say the minimum requirement for step is 6mm clearance from other apertures for the stencil houses that

Several years ago, we had almost same pbm, best results have been obtained by using water soluble paste (those time the old AM1208). Any way, to get a good toe meniscus is not so easy. Talking about CTE, keep in consideration the internal die of TSO

With a melting point of roughly 300°C, you would need to have the product see temperatures peaking around 325°C at a minimum. (I would make sure the components and PCB materials can withstand these temperatures) Most convection ovens do not go over 3

| I have a component that is glue cured on the bottom of a pcb. The component is a 1206 size jumper. It is made up of iron/nickel alloy. The problem I am having is that the part will fall off the board during wave solder. Is the component not abl

Hi all, (I posted on eevblog also, figured I'd try hear as well since this seems like a semi "niche" question) I need some advice on PCB cleaning. Up to this point, our assembly line has strictly run NC paste, with all SMT parts. We never washed an

Thanks to all for your input. We did have a third party do an analysis on boards from the first shop. They were shipped directly from the board shop to eliminate the possibility that we could contaminate them. The third party (Forsite) did find Sili

We are a company that designs a product but gets the PCB fabricated and the surface mount assembly done out of house. The product then comes in house and we test it, do some final assembly on it, and ship it. We recently had a prototype run of PCB'

There is a new toy I received today: a NeoDen TM-240A automatic desktop pick and place machine! I’ve kept my eyes on this baby for a quite a while, and finally decided to make a purchase last week. The shipping was very fast: DHL from China, a total

Is this a new design or have you manufacted these in the past without a problem. we manufacture ceramic arrays from X7R and COG, X7R has a differnet dialectric strength so higher capacitor values can be achived. With the introduction of RoHS the term
