Adhesive Deposition

When choosing whether to dispense adhesives with high-speed dispensing equipment or a stencil printer, a number of factors must be taken into consideration.

Web-based ATE Adapts to Test Future Technology

Easy access to test data and a broad range of tools for test program development are employed via Web-based technology.

Conversion Cost Update

When conversion cost is measured on a per lead basis, the evidence clearly indicates that the cost of transformation is declining.

Placement Equipment

Featuring unique centering and vision systems, modular designs and high throughput rates, today`s automated pick-and-place equipment is a far cry from the manual placement and handling machines of the past. Both fine-pitch and odd-form components can be placed on a PCB at the push of a button with some advanced machines. Other desirable options include small footprints, computer-compatibility and quick changeover times. SMT presents the following placement equipment selector roundup to highlight

High-volume Placement

The FCM, with speeds of up to 96,000 cph, has a footprint of 50 sq. ft. The slow movements of up to 16 independent placement modules, along with stationary feeders and boards, reportedly allow the unit to achieve a defect rate of less than 25 ppm, placing components as small as 0201. Vision modules allow placement of components down to 0.020" pitch.
