WebHASL vs. Immersion Gold We make electronic equipment used in corrosive environments. Experts suggest we use hot air solder leveling (HASL) as a finish on circuit boards instead of immersion gold. ... while the next would be the change from HASL to ENIG to create a lead-free product. ENIG boards can be problematic from the perspective of Gold ... WebThe rule of thumb we have been using is if you need a high solder reliability use ENIG gold, otherwise a RoHS friendly finish (either lead-free or silver or whatever the manufacturer recommends). However, a lot of what I have been reading seems to suggest the ENIG is great if we need to store blank boards for a long time, or if using BGAs which ...
WebThough many types of PCB surface finishes exist, we’ll be covering three well-known ones here — HASL, OSP and ENIG. 1. HASL and Lead-Free HASL. A HASL surface finish … WebMay 18, 2024 · Sn/Pb Hot Air Solder Level (HASL): HASL is comprised of solder with about 63% tin and 37% lead. The PCB is dipped into the molten alloy after solder mask is applied as hot air knives remove the excess, so a thin layer of finish is on the board. Lead-Free HASL: This finish replaces the lead with 0.6% copper and increases the tin ratio to …
WebThey do, however, have certain things in common. Both ENIG and ENEPIG employ immersion gold and electroless nickel. Both of these surface coatings offer a flat and straight surface. This makes it easier for manufacturers to install components on the surface of the PCB. Additionally, both ENIG and ENEPIG are lead-free.
