We have an assembly which we are trying to machine pick and place a Mil-Max pin that is .020 dia placed in a .026 hole. The board is .1125 thick. We have to place 106 of these pins. Without going into the challenge of getting proper hole-fill to me

There is an approximate 1W dissipation and has a 2 sq in area below part on solder side as a heat sink, vias are to physically conect this solder side area to power pad, so its necessary to use an adequate amount of paste. I really don�t think it has

Vias are thru hole, pcb is two sided, bottom copper is 2 sq inches, vias are 0.6mm diameter. thanks,

A quick experiment idea: Try reflowing a bare board prior to assembly. Perhaps your boards have moisture and outgassing issues.

Does anyone know of a secondary source for the 773 ND edge chain lube ? $63.00 a pint from Vitronics is pretty intense.

We have 5 ovens that we use this oil on. Its like $23.00 per pint from the manufacturer. But they say you have to buy a case of 24. I just went ahead and bought it from Vitronics.

Hi, We solder a part almost identical to this without problems. Could it be your airflow in your oven is set to high? On our prototypes we didn't place any solder on the middle bad as it was not a connection, and we did not need it thermally, how

I just bought some of XPM3 series. according to Vitronics, you shouldn't go through more than two quarts a year per each oven. Have you experienced this? If not then I too would be interested in a 2nd source.

We use a HEPCO model 3000-2 (hepcoblue.com) to shorten leads on various through hole components before we solder them on a pcb. You will have to verify they have a die that works with your particular LED module. If they do, this is what I would rec

I placed a Maxim MAX16810 38 pin TQFN with a power pad ground on the bottom of the chip on a prototype board FR4 doble sided. Vias of 0.6 mm where placed underneath part, 6 vias in total. Solder was placed with an air operated syringe, land pattern w
