What is Kester solder made of?
The roadmap recommends a solder alloy composed of Sn-Ag-Cu for board assembly.
Where is Kester solder made?
Kester recognized the importance of being a global supplier in the electronics industry by establishing manufacturing facilities in Singapore (1969) and in Germany (1972) to better service the Asian and European markets, respectively. Kester was acquired by Element Solutions Inc. in December 2019.
What is no clean flux?
No-Clean Flux actually means that the amount of residue left behind is negligible to the point where there is no need for it to be cleaned. Thus it is in fact just very low residue flux that does not require cleaning in most cases. To clean this No-Clean Flux residue Bittele uses a flux remover cleaning agent.
Does Kester solder have flux?
Kester 186 and Kester NF372-TB are also available in Flux-Pens® for optimum board cleanliness. 44 possesses excellent fluxing ability; the flux residues are non-corrosive, non-conductive and do not require removal for most applications under normal conditions of use.
Does Kester solder have lead?
25 for wave soldering. SOLDERTEC lead-free roadmap in Europe recommends alloy range SnAg(3.4-4.1)Cu(0.45-0.9) for reflow and wave soldering….Lead-Free Alloys.
| Alloy | Melting Point °C | Remarks |
|---|---|---|
| SnAg3.0Cu0.5 | 217-220 * | Predominant alloy in Japan |
| SnAg3.8Cu0.7 | 217-218 * | |
| SnAg3.5Cu0.7 | 217-218 * | Commonly used |
How does Chip Quik work?
It looks like regular solder, but is a lot more brittle. The purpose of this metal is to mix with regular solder, and keep it liquid for a longer time, to facilitate removing components soldered in multiple locations, like an SMD chip, or board with lots of pins. It keeps solder joints workable for 15 or more seconds.
Can flux residue cause shorts?
When flux is not cleaned off your connector, it can create a conductive path between pins where there should be no connections. Flux is a “leaky insulator” which means it allows electrical currents to leak between contacts, causing I.R. failures in the high-voltage test, and—in extreme cases—even shorts.
Is rosin core solder no clean?
You do not need to clean this residue, but it will be there regardless. Rosin flux is a traditional solder which is based on pine tree rosin. Roxin flux is active enough to solder electronic assemblies and the residue has a very good insulation resistance.
What is the best solder to use for electronics?

What is 951 soldering flux used for?
951 Soldering Flux. Kester 951 is a zero-halogen, non-rosin flux designed for wave soldering, conventional and surface mount circuit board assemblies. The extremely low solids content (2.0%) and nature of the activator system results in practically no residue left on the assembly after soldering.
What is keykester 951 flux?
Kester 951 is a zero-halogen, non-rosin flux designed for wave soldering, conventional and surface mount circuit board assemblies.
Is there any residue left after soldering 951?
The extremely low solids content (2.0%) and nature of the activator system results in practically no residue left on the assembly after soldering. There are no residues to interfere with electrical testing. 951 exhibits improved soldering performance to minimize solder bridges (shorts) during rework operations.
What are the benefits of 951?
The surface insulation resistance on soldered boards is higher than that provided by typical water-soluble fluxes. 951 contains a corrosion inhibitor such that no corrosion products are formed when bare copper surfaces are exposed to humid environments. Share Find A Distributor To Buy
