Precision Tapes

For almost 30 years Semiconductor Equipment Corporation has set the standard for high quality dicing tape. Tapes are selected for your application based on die size and blade thickness. Small die and hard to cut materials require higher tackiness, while larger die call for lower tackiness. Thicker blades require thicker tape.

Model 450 Hot Gas Rework Station

Bonded die or surface mounted components can be removed with this versatile rework station. Rework can be accomplished without disturbing nearby components or damaging the removed device. Removal heat is applied through an interchangeable nozzle. All process parameters are closely controlled. The versatility of this unit makes it ideal for removing surface mounted components such as leadless chip carriers, eutectic bonded die and epoxy bonded die.

  • Hot gas jet directs heated nitrogen through an interchangeable nozzle to the selected area on the substrate.

  • Idle heat and nitrogen flow through the hot gas jet minimize heater warm up time.

  • A voltage proportioning temperature controller monitors the gas temperature at the nozzle and controls it within a narrow range.

  • Gas temperature is adjustable to 800 º C.

  • Gas flow is adjustable. Flow indicator is mounted on the control panel.

  • Heated work holder eliminates thermal shock and prevents substrate cracking. Temperature controller with digital readout adjustable to 350 º C controls workholder temperature.

  • Interchangeable work chuck mounts on workholder to adapt to various package configurations.

  • Position lock feature holds work holder firmly while hot gas is actuated. Position lock override provided.

  • Push button and parallel foot pedal operation to increase nitrogen flow and temperature from idle to the amount required for die removal. Also actuates work holder position lock.

  • Pressure interlock in nitrogen supply line prevents a low pressure burnout of heater element.

  • One half inch Z motion (vertical travel) manually controlled to permit nozzle to reach into deep packages.

  • Nozzle height can be adjusted 1.5" to give a total range (combined with Z motion) of 2".

Die Ejector Systems

 

Model 4800 Die Eject Grid

A complete system includes a Die Ejector Grid (for .040 x .040 and larger die) mounted to a combination warming plate and vacuum chamber. A separate console houses a temperature controller, vacuum switch and power switch (see exploded view). Individual parts of the system can also be purchased separately.

In operation, a sawed or scribed wafer, mounted on a film frame or ring set, is placed over the grid, consisting of a series of closely spaced points. Vacuum and a low temperature (approximately 170°F) are applied through the grid to the back side of the wafer mounting tape. The vacuum pulls the tape from the back of the wafer into the valleys between the rows of points. Lifting the die from the tape with a tweezers, vacuum pencil or vacuum collet, is then a very simple matter. The Model 4800 will accommodate all film frames or ring mounting sets.

Model 4750 Die Ejector System

The Model 4750 Die Ejector ("poker plate") System solves the problem of quick and easy die removal from wafer mounting tape. It can be supplied as a stand alone unit or can be interfaced into your regular or high speed die bonding, pick and place or die inspection equipment.
