Robotic probers for the high-end semiconductor test industry can solve calibration problems facing automatic test equipment manufacturers.
These tools, which contain high speed, complex electronics, require a method to validate and calibrate their test signals. As test points have increased in number to the thousands, and chip speeds have increased in bandwidth into the GHz, robotic probing devices have automated the process under software control.
The family of robots now includes R-Theta and x-y versions for many ATE testers. The robots attach to the test head and probe specific pads on a device interface board. An on-board CPU moves the probe tip along high-precision linear bearings using optically encoded stepper motors for accurate positioning.
Series 91SC storage cabinets are constructed with 16-gauge, cold-rolled steel and finished with white, baked enamel. A clean, cost-effective and durable storage unit for cleanroom applications.
Will not crack or harbor contamination. Comes with five solid shelves in four standard sizes, with custom sizes available on request.
The autoplacer pick-and-place machine has over 300 feeders onboard to maximize flexibility and reduce or eliminate changeover times. Multiple jobs can be run on the placement machine without the need to stop to change feeders during production.
Can place components from 0201s to 55 x 55 mm at up to 21,600 c/h without a fine pitch placer or chip shooter.
BLISS STAT blue static dissipative work surface mats, made of a three-layer vinyl material, are designed for desks, tables and other surfaces susceptible to ESD damage. Now available in three sizes: 12 x 18", 18 x 26" and 20 x 27". All mat sizes typically ship within four weeks.
The matting passes flammability tests because it is made of polyvinyl chloride with additional flame retardant additives.
EVP-750 bare board loading station can be positioned at the front of the line or after a magazine line loader. Designed to load stacks of up to 170 PCBs or pass PCBs through from the line loader.
Has a precision extruded aluminum framing with painted vanity panels; standard features include a programmable logic controller, open architecture (front loading), load or pass-through models and left to right travel.
Also features:
· Master touch button control panel / Auto and Manual modes
· Reliable AC motor with variable transfer speed
· Hand crank width adjustment
· Operator controls
· Audible alarm and three-color light tower
· ESD grounding receptacle
· SMEMA Spec. 1.2/NFPA79 Compliant
· 14 Pin communication cable
Can handle products with a thickness of 0.045" (1 mm) minimum, edge contact of 0.118" (3 mm), above board clearance of 1.1" (30 mm) guard and below board clearance of 1.1" (30 mm).
Solder Coat Co. Ltd. (Nagoya, Japan) is introducing the GTS series of lead-free solder paste in North America and Europe.
The paste can withstand a preheat temperature of up to 200°C for 2 minutes. Does not require refrigeration for storage and transport, thus reducing handling care and cost.
