NexLev connector

Can anyone advise the best aperture opening and stencil thickness for Nexlev connector?We are seeing high reject for open solder.

BGA connector

If you have room, and the aperture size will allow for it, try a 5 mil overall stencil thickness with a 1 mil step-up in the area of the BGA connector.

Butt connector

From J-STD-001: Components designed for pin-in-hole application and modified for butt connection attachment, or stiff-leaded dual-inline packages (e.g., alloy 42, brazed or tempered leads) may be modified for use on Class 1 and 2 products but shall n

Blocking stencil apertures (on purpose)

Electronics Forum | Thu May 01 13:56:45 EDT 2003 | kmorris

Dave: After the stencil was made with apertures for a connector on this PCB, it was discovered that the connector would have to be handsoldered after SMT reflow. If the solder deposits are left to reflow on the pads, it makes it difficult for the o

Consider opening the stencil aperture to increase the amount of solder available to the connector leads.

Wave solder bridging

Do you glue SMT parts on the bottom? If so, use your SMT glue to prevent the short. Just cut a new stencil with 0.020" wide apertures between the pads of the connector (bottom side). We do it all the time.

Pasting through hole connectors

Electronics Forum | Fri Apr 21 12:43:51 EDT 2000 | David

We are going to hand place through hole connectors by screening them top side in a double sided reflow board. I saw this done before sucessfully on a daily basis but is there anyone with a paper or specs as to what aperture size, any special pad cons

REFLOW SOLDERING OF THROUGH-HOLE COMPONENTS

Electronics Forum | Mon Jun 24 18:45:06 EDT 2002 | jersbo

I have done experiments on small runs, with a few connectors and have had favorable results, I had apertures (oversized)made for the thru-hole connectors on our SMT stencil and hand inserted the connectors.. A few insufficient solders here and there

Interested in pin-in-paste process with standard ROHS connectors

Electronics Forum | Wed Jul 06 15:29:01 EDT 2022 | glasscake

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

Reflow soldering through hole parts

Electronics Forum | Tue Jan 30 12:03:15 EST 2001 | slthomas

Pete, I'm wondering how much optimisation you needed (or were allowed) to do with respect to connector design. The first one we evaluated had a row of leads that I can only describe as "crescent" shaped in cross section. Impossible to get even 50%
