Thermal relief question

Electronics Forum | Sat Jun 11 07:51:15 EDT 2016 | davef

Hi Steve ... There are arguments between fabricators and thermal relievers about adding non-connected copper tabs to barrels in hopes of providing thermal relief, but that's not what you're talking about, I believe. I don't foresee an issue moving t

We all know that whenever possible, we want thermal relief between the barrel/pad and the copper foil to make it easier to properly solder that through hole connector. My question is, assuming there is no connection from the barrel to a copper layer

Hi Dave, I'll ask them if they consider it on the next spin....can't see any reason it would have any negative effects. Thanks! Steve

Soldering to thru-hole lead to ground plane without thermal relief

I have 15 very large backplanes (.156" thick Au plating) that the ground pins of a high density thru-hole connector were not thermal relieved in the artwork. As a result we are unable to solder the 8 pins that connect to the ground plane. We know t

Did you try preheating the board then hand solder? Those little heat shrink guns work great for this.

IPC-610 Rev B: Paragraph 4.1 (page 52), As an exception to fil requirements on Table 4-1 on thermal heat sink planes plated through holes, a 50% vertical fill of solder is permitted, but with solder extending 360 degrees around the lead with 100% wet

Solder 'follows' heat. 1. Preheating is a great idea, use a baking oven to get the whole assembly up to temperature, use the preheaters in your wave solder machine (without wave) to preheat the assemblies ... 2. Or use the biggest soldering iron

A few more tricks to try: - Got a hot air rework machine? You can get more controlled heat on the area and lower the risk of damage to the fab. I never got topside fillets un unrelieve ground planes until I went to convection preheat on my waves.

KIC thermal profiler

Does anyone out there involved in RF manufacture have any experience with the KIC Slim-Kic profiler? Do you find any interference problems between the RF transmissions and the testing of your products. We build primarily high-freq stuff like point-to
