Cleaning old built up flux residues from reflow oven

Electronics Forum | Thu May 01 06:42:25 EDT 2014 | cbeneat

I use Simple Green, works pretty well, although I use the concentrate and don't dilute it as is recommended, so it's pretty strong. I am going to try the sugar water though. I'm intrigued.

Combining two similar footprints - absolute no, or might work - tips to improve odds?

Rather than using an over-lay of both pads, I would just stay with a rectangle pad shape, a little wider to accommodate both footprints. Keep it simple.

Is it just me?

You will have to open each parts Shape Data, Click on the Shape Process tab, Click on the Process tab, towards the bottom of the page under Error change the Dump Position to Box. This should work. Good luck.

Hi, If you can advise any assembly issues or concerns regarding this type of part and also... 1 - Can you confirm that they come in tape & reel format? 2 - Is it a requirement to have a glue dot in the centre of the pcb pads? Thanks, AJ...

Mechanical Delamination at de-panel

Electronics Forum | Tue Jun 10 21:15:01 EDT 2014 | comatose

We had a similar problem once, it was due to insufficient v-score depth. While waiting for remade PCBs we would run an exacto knife along the score lines prior to depanel to cut a little deeper. Not ideal for sure, and not fast, but it worked.

Solder mask peel from traces, post wave solder. Etchant residue?

Hi We had the same problem but it turns out the problem is with the supplier we use a water base flux too, supplier change the solder mask and it work. cheers!

Your target ppm in on the Juki machine a take it. So it's rejecting these parts due to the inversion? Any way to disable this. A right-side down resistor is not ideal, but it will certainly work electrically. Reese
