Chemical Metal Cleaning

Acid and Alkaline Cleaning

Chemical cleaning for sheet metal has two different processes. Not all sheet metals require both cleaning processes.

The two cleaning steps are alkaline clean and acid clean.

Alkaline is the first step when preparing to etch metal that requires both cleaning processes.

Alkaline clean is used to remove all oils and organics from the surface.

Acid cleaning is the second cleaning step. An acid clean is used to remove any contaminants that remain on the surface. Some metal surfaces will be micro-etched from this chemistry which helps with photoresist adhesion.

The cleaning process is essential to attain your ceramic and metal etching goals.

If the surface is not properly cleaned the photoresist will not lock into the material. This means when the material is being etched the photoresist will lift causing your parts to fall outside your tolerances.

A second reason for cleaning the surface is to remove all dirt particles. If these particles are not removed, they can interfere with the exposure step. Causing opens for PCBs or etched areas that were supposed to be unetched for chemical milling/glass etching.

Electrolytic Cleaner for PCB

Electrolytic cleaning is a common cleaning process for the fabrication of PCB. Electrolytic cleaning is used to remove the chromate layer on PCB / copper foil.

Cleaning copper foil electrolytically before micro etching is important to make sure the chromate layer does not interfere with the micro etching process.

Ultrasonic Cleaner Machine

For the customers that require a VERY clean product, we offer an ultrasonic cleaner. The most common use of a Chemcut ultrasonic cleaner machine is for cleaning PCB.

Multi-layer PCB boards need to have perfectly cleaned holes to make sure there is no break in the copper connectors. Therefore, PCB fabrication shops will use an ultrasonic PCB cleaning machine to clean the holes out.

Mechanical Metal Cleaning Machine Options

Our mechanical cleaners were first used to scrub PCB surfaces.

The scrubber is less aggressive compared to the deburr. It is used for cleaning the metal surface and creating a uniform, parallel grained-finished surface.

The mechanical deburr is typically used on rigid metals and PCBs after drilling to deburr the holes. Deburr is more aggressive than the scrubber and will result in a uniform, parallel grain-finished surface like the scrubber.

The scrubber and deburr have both evolved into a mechanical glass cleaner, wafer cleaner, and metal cleaner for chemical milling
