Hi, I'd be inclined to go with the through hole capacitor, as to surface mount it you would probably need to go for an elco (ceramics & films don't do that value in that voltage, & you'd be hard pressed to get a tant in that voltage). SMD Elcos a

Hi , We are having Pin hole issues on the passive locations in the board after the SMT reflow process. Details: PCB surface Finish : ENIG . Solder paste : Alpha OM338 – M13 / Indium SMQ92J Location : Its Random and more on passive components. {

Rich: In my experience, I have seen three cases of SMT Capacitors cracking: 1. Due to thermal shock when entering the wave solder. Note that these were 1210 package sizes on the wave solder side of the boards. We were able to trace this back to th

We are running Clean process. solder beadings were found after the wash process. Weird eh!! It's true.. Details: 1)wash pressure ? No shadowing effects from high profile component. It also happened on the component's body of the 1210 & 0402 caps whi

I recently bought a DEK 265 Mark 1 on the used market for $1,500 dollars along with a ABW 1210 Reflow oven which I really wanted. I knew the DEK had not been refurbed but that was fine because I was willing to pay there extremely high prices to have

Genny, you may want to look at the brds you will be running and identify the various packages. I do not know what a standard package is. Most chip resistor and capacitors, 0402, 0603, 1206, 1210's are on 8mm feeders, but ic's vary quite a bit. Also r

For now, on this first board, we will be reworking components such as 0805 and 1210 size caps and resistors, along with SOT-23 and SC-70 size packages. We might eventually get into BGAs. This board will most likely be a double-sided board, probably

Hi Dougs, I think I'm going to have to admit to some insider knowledge here. It kind of gave it away when you mentioned there were only catalogue pages instead of specs. http://www.anglia.com/product_search/part_tracker/index.asp I think you may

Hi Paul M, There are no silly questions but silly answers.. and here is maybe a few if I understand you correctly: If you consider place anything less than a 1.27mm (50mil) pitch component down or a chip less than a 1210, hey it maybe don't even work
