Sniper-WB “Wide Body” Split Vision Rework System SMD-7007

Overview

Sniper-WB

The Sniper-WB Wide Body will rework PCB’s as small as 2” x 2” and as large as 20” x 24” (508 x 610mm) {larger on special request}. Its powerful under board heater stabilizes the entire PCB and gently retards the warping of large PCB surface areas. This is achieved by a 3600 Watt high energy convection Panel Heater and a 1200 Watt Reflow Heater, total energy is 4800 Watts.

Low Temperature Benefits

The high energy capacity of the Sniper-WB reduces the temperature required to reflow. This feature is important in reworking TBGA components. The surface of these components are often metal and can warp if exposed to high temperatures for extended periods. Once the chip is warped it cannot recover.

Many other components can benefit from this feature, CCBGA, PBGA and large QFP packages all demand simultaneous collapse and moderate reflow temperatures.

Programming and Operation

For a more detailed description of temperature profiling and operation refer to page 18)

XY Table

In addition to the importance of high energy and greater bottom coverage, the Sniper-WB includes a sleeve bearing XY Table with ledge support rails for the PCB. Steel support rods are used to prevent board sag and warping. The standard Board Holder supplied is 20” x 24” (508 x 610mm)

The Sniper-WB includes a sixteen (16) profile, sixteen (16) segment controller, which is easily programmed using an integral key pad. Alternatively the system can be controlled via an RS232 connection with an external computer. (See page 18).

Axis Adjustment

Sniper-WB Order Information

Micrometer XYZ adjustment is provided on the Board Holder with a motorized Theta axis switch control. Theta in this manner is always “true” and referenced to the component not the PCB.
