Hello, Hoping for some recommendations for how its best to selective solder clinched PTH components.. We are using Ersa equipment. Problem we are having is some of the leads are holiding `blobs` of solder on their leads. Have tried single dot

Does anyone have a printable ruler for measuring smd/smt tape and reel components? I currently have one that measures 2 pitch and 4 pitch but it is small and only measures up to 75 parts at a time. I would like one to also include 8 pitch.

Hi, This is a first step before you enter this info into component library. But this step is optional if you have enter this info before and you have a right tool to check your and simulate PCB manufacture.

I thought this thread was about someone wanting a simple guide so they can train their operators on polarity for a wide range of components, not a software package for programming. I am confused, but that happens from time to time.

Hello All, Are there any documents that list component spacing requirements in terms of DFM/ DFA. I was going through IPC website but wasn't able to find any. Thanks!

For vertical mounted, axial leaded components; the standoff from the land to the component body should be 0.4mm[0.016in] to 1.5mm[0.059in]. Right?

Pls share with me the time cycle result for the THM component on board thickness 93 mils, I would understand the risk for not having to achieve soler barrel fill less then 50%.

The top PoP part is what gets dip fluxed or dip pasted. We have had warping issues with these components before but it is almost always the top part. My guess would be bad components if your reflow profile and print process is good to go.
