There are many types of etching equipment, which one should I choose?
Even when looking at the specifications of etching equipment, it is difficult to tell the detailed differences, and it is easy to make decisions based on price.
Let's choose the best etching equipment from Sanhayato!
Here are three easy-to-understand differences between etching systems.
1. microcomputer control vs. analog control
Microcomputer control is recommended when workability, reproducibility, and safety are important.
The liquid temperature, transfer speed, etc. can be adjusted on the panel, and since it is digital, the same conditions can be reproduced.
Safety mechanisms are also standard, so that even if someone unfamiliar with the operation can operate the machine, he/she can rest assured.
With analog control, each setting is made individually, which makes work complicated, and because the setting method is manual, such as turning a dial, it is difficult to completely reproduce the same conditions.
2. spray type and air jet type
During etching, it is desirable to keep the liquid flowing to achieve a quick and clean finish, and to keep the substrate surrounded by a fresher liquid that contains as little dissolved copper as possible.
With the spray method, the substrate is moved by conveyor transfer while being sprayed with the solution, which allows the solution to circulate forcibly, resulting in a shorter turnaround time than with the soaking method.
The pressure of the spray also produces a sharper finish.
In the immersion (batch) method, where substrates are immersed in liquid, air is supplied to the tank to circulate the liquid since the liquid does not flow simply by leaving the substrates in the tank. This is labeled the air jet type.
3. one tank type and two tank type
Etching uses chemicals to dissolve metal, so if the etching process is left unattended with chemicals on it, the pattern that has been created will dissolve.
After etching, it is necessary to rinse the etched area with water.
The two-tank system consists of a spray etching tank and a rinse tank, allowing the work to be performed in a single step.

When we delivered ES-800M to Kyushu Vocational Ability Development College in the past, we received this kind of feedback.
We use CAD/CAM systems to manufacture printed circuit boards, which is the role of electrical and electronic systems in manufacturing.
In the process of "exposure, development, and etching," 20 students are able to produce each printed circuit board smoothly without waiting for a long time.
In the future, it would be even better if the maintenance and management method of the etchant could be improved.

I think there are various conditions and needs for etching equipment.
Especially for the ES-800M and ES-850M for corporate customers, about half of our deliveries are customized products, and we have been able to provide products that better meet the needs of our users.
Please contact us for more information.
Example of production

Motion sensor light
This is a sensor light using a motion sensor. It lights up when it detects a person.
This is a multi-measuring device with a barometric sensor board, humidity sensor board, temperature sensor board, and ultrasonic sensor board on the motherboard.
