What are the advantages of water-based cleaning agent in SMT process cleaning?

Water-based cleaning agent cleans oil stains and grease by wetting, emulsifying, permeating, dispersing and dissolving surfactants, emulsifiers and penetrants. Water-based cleaning agents can also be simply described as water-soluble cleaning agents that can be diluted with water, such as the detergent we usually use. But the water-based cleaning agent mentioned here is mainly used for industrial cleaning.

With the miniaturization of electronic components, component mounting and high-density structure, the introduction of lead-free technology, and increasingly strict environmental and material control, the rapid development of water-based cleaning agents has been promoted. At present, the application of water-based cleaning agent in SMT process is very mature and shows considerable advantages.

First, off-line cleaning of SMT printing screen

1. Suitable water-based cleaning agent product: neutral water-based cleaning agent.

2. Cleaning objects: solder paste residue, uncured red glue residue and misprinting board cleaning before reflow soldering.

3. Cleaning equipment: ultrasonic steel mesh cleaning machine and spray steel mesh cleaning machine.

Second, online cleaning of SMT printing screen

1. Suitable water-based cleaning agent product: neutral water-based cleaning agent.

2. Cleaning object: it is mainly used to clean the solder paste residue on the screen board and misprint of SMT printer.

Third, reflow oven wave soldering oven cleaning

1. Applicable water-based cleaning products: alkaline water-based cleaning agents (barrels, watering cans, aerosol filling, etc. ). See 2. Cleaning objects: all kinds of flux residues, rosin, oil stains and other stubborn residues baked in the reflow oven and wave soldering oven.

Fourthly, SMT welding fixture/carrier cleaning.

1. Suitable water-based cleaning agent products: alkaline water-based cleaning agent.

2. Cleaning objects: cyclone separator, welding fixture, fixture, baking flux on condenser tube, rosin, oil stain, etc.

3. Cleaning equipment: fixture cleaning machine and spray cleaning machine suitable for cleaning the external surface of the workpiece.
