433 FLUX TYPE RMA
This flux is mildly activated and is suitable for automatic soldering of PCB's used in communication, defence and space application equipment and also for a wide variety of electronic soldering application. It's activity is slightly higher than R type. It is capable of providing substantial improvement in wetting of oxidised surface and able to effectively control surface tension at solder - PCB interface leading to smaller solder fillet and reduction in solder defect. These are excellent foam fluxes and can also be applied by dip, spray or brush. The flux residue left after soldering is non-conductive and non-hygroscopic. For cleaning the residue use HYBRID # 1000 series cleaning solvents.

515, 529 FLUX TYPE RA
Suitable for both hand and automated soldering of plated through hole and surface mount devices. It is a fully activated rosin flux and could be used on all critical electronic assembles, especially when oxidation level in PCB's and components is non-uniform. These are suitable for soldering metals coated with cadmium, copper, gold, silver and tin. The residue is non-hygroscopic and non-tacky.

533 FLUX TYPE RA - LOW SOLID
Suitable for both hand and automated soldering of plated through hole and surface mount devices, it is a very high purity RA type flux that can be used on all critical electronic assembles, especially when oxidation level in PCB's and components is non-uniform. Its low solid content results in low residue. Specially formulated for foam fluxing of PCB's, and also for SMT applications, it is dependable for soldering on copper, brass, copper bearing alloys, tin plate, cadmium and gold plated surfaces. With low capillary action of raw flux, but good capillary action of solder, it provides instant wetting, less rejects and fewer touch ups. Though this product is active (RA category), cleaning effort to remove its residue would be much less in comparison with R or RMA type flux.
