~The Story of “Departure and Arrival”~
Newlong Seimitsu Kogyo's screen printing machine has the following operation switches.
This phrase "○○ removal and application".
It's a phrase that comes up frequently in our company. What are we "removing" and what are we "applying"? From an outsider's perspective, it may seem like a strange word.
In fact, there is a clear definition of the word "removal" within the company.
We define "removal" as "a mechanism that supports plate removal". However, if you write "a mechanism that supports plate removal" in the name of the operation switch, the number of characters will be too long to fit.
In this regard, I think that the phrase "removal and application" is the best phrase to express the function.
However, we are the only screen printing machine manufacturer that uses the word "removal and application" as the name of a similar function. Other companies seem to call it "peel-off" or "off-contact."
So, why does NEWLONG use "removal and application"?
This is closely related to the history of our screen printer development.

This is closely related to the history of our screen printer development.
In screen printing, the screen plate must be peeled off from the substrate after printing.This is called release.Since the beginning of screen printing, a clearance (also called a gap) has been provided between the screen plate and the workpiece, and the tension of the screen plate has been used to release the plate.
This is because the screen plate itself has a plate release mechanism, so no special mechanism is required for plate release.This printing method is still commonly used today, and is considered to be one of the reasons why screen printers can print easily compared to other printing methods.
However, with the passage of time, the size of the screen plate has increased, and high-viscosity ink such as conductive ink has come to be used. .
When the company was founded, our screen printing machine did not have the idea of a "plate release mechanism."Therefore, an engineer at the time, who wanted to do something about plate separation, used a spring to develop a "plate release support device" that could be retrofitted to the printing presses of the time. (Figure below)
At the time, this device was sold in large numbers as a device that could be easily retrofitted to existing equipment and could dramatically improve print quality.
Therefore, it was named as an independent device rather than an accessory to the printing press.
Since it is a device that uses a spring to release plates that are in close contact with each other, we examined two options, one for attachment and detachment, and the other for attachment and detachment. It was named "departure" because it resembled the appearance of taking off.

At first, the word "detachment" was used as the name of the "plate detachment support device", but later, the entire "mechanism that supports plate detachment" came to be called "detachment".
And what used to be just pulling up the screen plate with a spring is now being controlled by a motor to perform complex movements.And the name is not just "take-off", but now various take-off methods such as "single take-off", "end take-off" and "double take-off" have been developed.
This "detachment" enabled high-precision printing, and raised the status of screen printing as a manufacturing method for electronic components.

Further development "Detachment and arrival of Newlong Seimitsu Kogyo"
Detachment technology is important for high-precision, fine-line printing. The current take-off and take-off conditions can be set according to the characteristics of the ink to be printed. Since ink is a non-Newtonian fluid, it exhibits various behaviors depending on the blending of fillers, binders, solvents, etc. mixed in the paste. In particular, when the plate is separated from the plate, shear speed occurs due to shear between the ink and the plate, causing the viscosity of the ink to change. If this is controlled with high precision by the release/detachment conditions, it is becoming possible to print fine lines of 10μm in width.

Newlong Seimitsu Kogyo will further refine its "detachment" technology and aim for high-precision screen printing.
