Q1- Will we be able to select the materials (flux and alloy) and run the process depending only on ourselves, distributors� help, machinery documentation, web data and �trial and error?� A1- Your materials suppliers [eg Kester, Alpha Metals, etc] wil

Good morning, Once again a met annoying solder beading issue while producing board with PLL (leadless, contacts from the bottom side of the package). Board has very high placement density and beads appear near PLL package only. This package is finep

Depending on model and/or series, each one has it's own specific manufacturing guidelines you must meet in order to get a successful solder joint. Then you must couple that to what your soldering process is. Assuming you are talking all thru-hole,

Sorry, I have not read the article. However, I do have five years experience constantly tweaking an AOI system that ran ONE product! The strength of the machine was solder inspection. The biggest problem was component color variation and shadowing

Hi First I think you have to analize your PCB design. Heavy weight components should be gathered on one side of PCB. As I think, if you want to reflow both sides simultaneously there might be a problem. A chance that large components will drop off

We too are having issues with our soldering iron tips. We purchased the new Weller WD series irons which we were told would work just fine with lead-free solder. The Weller unit has changed 3 times in the last year(latest unit is the WD2M series).

After some precursory experimentation, I am planing on employing a form of low melting temp solder for use in reworking some very dense, copper core PCB's, both SMT and THT, which were originally mounted with 63/37 solder. The main problem with the

From what I see, you have a couple of options... 1. Hand solder the secondary side LED's. This is only a good option if you're going to be at low-ish volumes. Higher volumes tend to necessitate more automation to reduce production costs. However

We always apply solder paste to either the PCB pads or the BGA balls. I have found that only using liquid or tacky flux does not always ensure proper wetting of the pads. Also The BGA sits closer to the PCB making cleaning and endoscopic inspection

Anyone have experience wave soldering rigid flex assemblies? I've just picked up a new job from a customer; it's a rebuild for the company, but new to me. The customer had previously taken their business elsewhere due to delamination problems with
