Selecting Xandex Inking Systems

Which Xandex DieMark Inking System is right for you?

Xandex DieMark® Inking technology revolutionized die marking at wafer sort and has set the standard worldwide since 1981. DieMark Inking Systems are available in Electric and Pneumatic models and utilize convenient, disposable DieMark Ink Cartridges to streamline and optimize the process of marking defective die. With models available for nearly every test platform and configuration, Xandex inking systems are in operation daily in every corner of the world where wafer sort is performed.

All DieMark Inking equipment is built and tested to a demanding quality standard at our California manufacturing plant to insure that no matter what DieMark equipment you choose, it will operate with "around the clock" efficiency and dependability.

Xandex Electric Inking Systems

Electric Inking systems deposit ink dots through actuation of a solenoid, which in turn moves the DieMark cartridge nylon filament up and down. Filament movement draws ink down the filament from the cartridge reservoir to the wafer surface. DieMark cartridge needle size, filament diameter, filament length, and ink viscosity are factory tuned. A standard ink reservoir is combined with a variety of needle and filament configurations for different applications and dot sizes. A wide range of Electric Inker models are available along with a variety of cartridge holders (solenoid and cartridge holder only). All use DieMark disposable cartridges. Many holders are designed to retrofit other manufacturers marking equipment. Retrofit of an existing inker is an inexpensive way to utilize the convenience and reliability of DieMark ink cartridges.

Xandex Pneumatic Inking Systems

Pneumatic Inking systems incorporate the convenience of DieMark disposable ink cartridges with the reliability of a microprocessor-controlled pneumatic dispensing system for the ultimate inking solution. Ink dots are deposited via pneumatic actuation of the inker shuttle mechanism and a simultaneous pulse of air into the cartridge reservoir. There is no filament and no direct contact with the wafer surface. A prober signal to the controller initiates the inking sequence, actuating the shuttle mechanism downward and sending an air pulse to the cartridge. Dot size is determined by adjusting a controller setting to change cartridge air pulse duration without changing the cartridge. Pneumatic cartridges are factory tuned, ensuring consistent dots and contain 40% more ink than DieMark filament cartridges.

Ink and Cartridge Types
The heart of any Xandex inking system is the patented DieMark Ink Cartridge. Pre-filled, factory tuned DieMark disposable ink cartridges are easy to use and require no adjusting, refilling or cleaning. All inks utilized in DieMark cartridges are selected to produce consistent dots over a wide range of speeds without dripping, or skipping. Listed below are the primary cartridge and ink types offered by Xandex. PPM = Parts Per Million.
