Hi, we use om338 from alpha metals in our smt production lines.I wont change this solder paste with kester em 918.Is anybody use this solder paste?what yo think abaout this paste.Is it good?

Hi, we have about 100L kester 108 - soldering flux thinner.That is thiner for Kester 2235 and some other fluxes.But we have not use this flux already, and I don't know what I can make with the tinner.Could you help me - what is chemical composition

I have heard the term as both green stick and orange stick, but yes, pushing on the leads to detect un soldered leads. The amount of force is subjective. Any thoughts on this is appreciated.

We call this the "orange stick test", but who's coloring? In preforming the test, you're supposed to use a light touch. Unfortunately, it's difficult to calibrate a "light touch." So, operators often end-up using too much force when probing or usi

Hi, We have a board with over 100 chips (mixed size) and some long Connector DIP through out Wave solder with many issues of no solder and solder bridge, (using clean flux with bubble fluxer and Kester solder bar). Currently we tried to reduce the de

Thank you ProcEng1 Nordson sent me a flux suggestion list: No Clean: 1. Kester Select 10 2. ALPHA EF-2210 3. AIM FX-16 Water Sol: KESTER 2331-ZX Nozzle Tinning: SUPERIOR #75

Kester sells preforms.

With DIP type components, a sub-par fluxing method (foaming a no-clean), and a chip wave where one is not needed are formulas for bridging and insufficient wetting. If you have SMD's on the wave solder side of the board greater than 0603, and no SOT

I think Steve is on to it. The wire is not getting hot enough to wet. Either the solderer is attempting to solder too quickly, or the PTH is connected to a ground plane. The solder sticking up through the hole leads me to think it's connected to a

Hi All, Just have a share with you guy. We are using T4 solder paste and also E-Stencil. We ahd try out Alpha, Kester, AIM and Qualitek. The result show Alpha had a very very heavy stack flux and can't get it clean off even by chemical
