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.

Rotary Head

The SI-E1000 compact chip mounting machine features the Planet Head. Reportedly, this compact rotary head achieves precise, high-speed placement by controlling its planet gears with a fully closed rotary servo. Bidirectional head rotation is said to support optimal head control and reduce operating cycle time. The head features reflective and transmission part recognition.

Touchless Centering Placement Heads

The PlacePro Model 7100 employs six touchless centering placement heads mounted on a single gantry. It can reportedly place a wide range of component package types at rates up to 18,180 cph. A high-speed scan camera mounted on the gantry below the head assembly provides on-the-fly vision alignment of components as the gantry moves from the pick point to the placement position. Touchless component centering is performed using the high-speed vision processing system and either the scan camera or o

Fine-pitch Vision and Dispenser

This head is capable of placing components ranging from 0603 to 32 x 32 mm, at a rate of 8,000 cph with an accuracy of 70 µm at 4 sigma. To place larger parts (up to 55 mm), the system uses a second head for pick-and-place at a rate of 1,800 cph with an accuracy of

Short Production Runs

MY9, the smallest footprint of the MY-Series machines, can handle up to 112 8 mm feeders, 105 SOIC tubes, or 80 8 mm tapes and 32 JEDEC trays with the optional tray exchanger. With this option and the new dual vision system, the machine is capable of placing components, QFPs, BGAs, and more advanced package technologies like flip chip, BGA and CSPs with pitch down to 0.16 mm.

Speed Enhancements

The 3Z is the latest version in the Contact 3 Series of SMT placement machines. Several speed enhancements reportedly have increased the maximum placement rate by more than 60 percent (13,000 cph). Faster motors with non-contact linear encoders are said to have increased head speed by 167 percent and table speed by 52 percent. Servo-driven Z axes increase cycle speed while improving placement force control. The unit retains its split-axis design with independent dual heads, 100 percent vision ce
