The HGRS-1J is a compact, economical single-jet tool giving high temp performance without "the extras". This is a great solution for specific applications (thermal test, fiber attach, small die removal) and for labs needing more thermal performance than air heaters can provide.

The HGRS-V is a highly adaptable dual-jet "thermal workbench" with a comprehensive suite of circuit-protective features. It's the ideal solution for those facing a variety of rework tasks involving large die, eutectic attach, double-sided devices or other assemblies with tight thermal constraints.

Available models

HGRS1J

Compact, economical single-jet version of the HGRS system.

Identify By: The mounted single jet and work-holder distinguish this self-standing unit from “Midas N2 Subsystems” sold to OEMS for installation on automated assembly equipment.

Problem Areas:

  • Status:  Operational, Current Production
  • Support:  Excellent all components current or replaceable by current production.
HGRS-V

In 2010 we designed a more rigid shear system with vertical adjustment, greatly increasing options for accessing difficult-to-reach components. The new systems has a stronger lead-screw and carriage, increased travel, and is coupled to a non-slip chain and sprocket drive.

Identify By: Link chain and sprocket drive on back of machine shows vertically adjustable shear mechanism. N2 flood arms are relocated to upper front corners of sub-cabinet, and light guides bolt to cabinet shelf - so the "Gold Ring" is gone from the sub cabinet face.

Variants:  Longer travel D5L8 (8") and D5L12 (12") versions are available.

Problem Areas:

  • Status:  Operational, Current Production
  • Support:  Excellent all components current or replaceable by current production.
HGRS-V

Customer feedback led to two HGRS-V improvements, a more ergonomic position for the operator shear knob, and a lead-screw-driven fine positioner for the work-holder.

Identify By: Right front corner shear knob, right side X-positioner knob, integral sub-cabinet with gold light guide mount, fixed-height shear mechanism. The right side knobs set these machines apart from earlier ones. Transitional units and retrofits to earlier machines are identifiable by a plugged hole in the front center of the cover where the earlier shear drive was located.

Problem Areas: Limited vertical clearance between top of work-holder and shear rod, caused as work-holder stack was raised to provide more heater block clearance for higher temperature preheat operations. Belt-driven shear can slip under heavy load.

  • Status:  Operational, lacks vertically adjustable, chain-driven shear mechanism
  • Support:  Excellent all components current or replaceable by current production.
HGRS-V

The HGRS-IV had limited room for handling large parts- so the HGRS-V was designed with much more clearance. Vertical space between work-holder surface and shear tool is open as far as the shear belt and cabinet supports. This model also was the first supplied with our H5JAJT05 pure tungsten, tight-wound filament heaters.

Identify By: Center front-mounted shear knob, faceplate logo, wide stance cabinet support, integral sub-cabinet with gold light guide mount, fixed-height shear mechanism.

Variants:  ou may find a few center knob machines with work-holder X-positioners, added as an option late in the production run or later retrofit.

Problem Areas: Center-mounted shear knob proved unpopular with some operators, belt shear drive can slip on high-shear applications. Earliest models still had ball-bearing horizontal positioners which become gritty and allow nozzle movement. Manual X-movement of work-holder proved crude for working between closely-spaced wire bonds.

  • Status:  OOperational, lacks X-positioner and other later refinements, but these are retrofitable options at overhaul.
  • Support:  Excellent all components current or replaceable by current production.

HGRS-1J Introduction

HGRS-V Hot Gas Rework Station

  • Semiconductor, Solar & Electronics
Midas Technology Inc.We're a made-in-USA manufacturer, specializing in equipment used to rework or inspect "Hi-Rel" (high-reliability) microelectronics. Midas-pioneered advanced rework processes are now in common use worldwide, supported by a network of exclusive distributors and sales representatives. We provide two vital capabilities for Hi-Rel rework: "De-Lid" (removing lids from hermetic packages) and "Hot Gas" removing specific components with precision application of hot gas. Our systems accomplish this without changing package dimensions and without contamination, vibration or thermal damage.
