CONFORMAL COATING VALVES

Conformal Coating Valves

Anda manufactures a variety of conformal coating machine valves. Our conformal coating valves can be utilized in a number of different configurations and spray patterns to meet manufacturing application requirements for coating of printed circuit board Assemblies (PCBA’s).

Atomized Conical Spray Valve

SA-W6L

Conformal Coating

The SA-W6L atomized conformal coating conical spray valve is the workhorse of the ANDA conformal coating nozzles. The SA-W6L can coat up to 80 to 100% of circuit boards depending on their complexity. It provides a repeatable, concentrated conformal coating film in a fine, circular cone spray pattern with coating widths ranging from 4 – 12 mm (0.15 ~ 0.5 in).

Needle Dispense Valve (Non-Atomized)

DJ-01

Fluid Dispensing, Conformal Coating, Potting, Encapsulation

The DJ-01 needle dispense valve (non-atomized) is a versatile dispensing valve for single-component bead, dot, potting, conformal coating or encapsulation projects. The DJ-01 is most commonly used in junction with the SA-W6L to conformal coat complex areas of circuit boards that are hard to reach and require a higher degree of accuracy. Dispense widths of 1 – 2 mm (0.04″ – 0.08″) and accepts a wide range of replaceable tips.

Atomized Needle Valve

ZS-02

Conformal Coating

The ZS-02 atomized conformal coating needle valve is a highly versatile conformal coating applicator that supports a wide range of fluid viscosities and is ideal for solvent or non-solvent fluid formulations. It is specifically optimized to atomize coating materials delivering an ultrafine needle spray pattern 2 – 5 mm (0.08 – 0.2 in) with exceptional edge definition and uniform coatings at high speeds. Long service life and improved design reduces the sealing ring replacement frequency for easy maintenance.
