Hakko HJ4000 – SMD Rework Fixture (without Hot Air Station or Pre-Heater)

Hakko HJ4000 – SMD Rework Fixture (without Hot Air Station or Pre-Heater)

The Hakko HJ4000 SMD rework fixture is a cost effective solution for manual SMD rework using split vision alignment precision and can be used with select Hakko hot air rework stations and IR preheaters for a complete low cost SMD rework system.

The HJ4000 fixture is designed for the printed circuit board to remain stationary while the head assembly is moved to accomplish the x, y and theta alignment. The gantry and frame base is constructed with lightweight extruded aluminum for cost efficiency and accuracy, while high precision linear bearings offer smooth x, y and z positioning.

Other features include quick release brakes for quick positioning, and fine adjustment controls for perfect alignment, +/- 100 microns, including theta.

The Z axis has a safety stop to limit movement and prevent the nozzle from contacting the top surface of the printed circuit board when lowered into position.
 

SPLIT-VISION SYSTEM

The split-vision alignment capability of the HJ4000 allows you to accurately place SMD components as large as 45mm square down to 1mm square. And real-time viewing of the alignment is accomplished using a high-resolution color camera, lens and prism system.

Use the high-quality macro video lens for close-focusing up to 6X optical zoom, while the camera module features a 10X digital zoom capability.

The bottom-side of the component is illuminated with “white” dimmable LED lighting while the target location on the PCB is illuminated with “blue” dimmable LED lighting. Top and bottom lighting are then independently adjusted to provide optimal contrast for the user between the two images.
