The Application of Longer Intelligent pump in the manufacture of Microchips08-28-2020

How is a Microchip Made

A microchip, commonly called the integrated circuit, is a tiny electronic circuit. It is made up primarily of semiconductor devices. Microchips are the core of modern electronics used everyday.

To manufacture these microchips thin-films are deposited, coated, developed, etched and measured-- transforming the electrical properties of these complex devices. This process is done over and over again.

What kind of support can Longer provide for the Chip Manufacturing

Longerpump, as a supplier of precise fluid transfer and handling devices, our products and comprehensive services are used wherever the fluid transfer requirements are high accuracy and reliability. For the key processes in the manufacture of microchips - Coating, Etching and Development, our product portfolio is ideal for the important process chemicals transfer.

The application of Longer Intelligent pump in the coating process of Chip Manufacturing

The Customer Requirements

-- Pumping medium- acid and alkali liquor

-- Flow rate-dozens of medium ml / min, depends on the coating thickness

-- Flow rate precision of pump can be achieved up to ± 2%

-- High coating uniformity

-- Customize parameters by programming, and the parameter programs can be stored and easily recalled

-- Process flow

Pumps are used to transfer the acid and alkali liquor to adjust acid-base balance in the coating liquid, then the liquid through sprayer is sprayed onto the chip.

The Highlights of Longer Intelligent pump

- A large touch screen and user-friendly icon-driven software make setup quick and straightforward.

- According to different chip coating thickness requirements, different filling parameters can be saved as a program, which is convenient to be called directly for later use.

-The pump has programmable function, allowing the operator to program constant dispensing, appointment start, alternate directions, and adjust flow rate with time to the needs of the application.

- When pumping fluids, the fluid only comes into contact with the bore of the tubing, and PharMed® BPT Tubing has very good general chemical resistance and excellent acid, alkali and oxidation resistance, it is ideal for the process chemicals transfer.

- Longer Intelligent pump can be controlled through touch screen, foot switch, analog signal and communication commands, combined with a variety of interfaces (USB, RJ11, DB9 etc.) for easy system connection.
