Description

Heat Block Insert is a Wirebond tool that is made up of a frame supporting face and a die pad supporting face and used as a leadframe support plate during the Wire bond process.

The Heater Block Insert features a mounting platform designed to accommodate a lead frame and a die that is attached to the lead frame. The heating element of the Heater Block Insert includes a centralized heating surface and peripheral heaters around the centralized heating surface. This allows the selective heating of the locations on the lead frame in preparation for wirebonding.

Oricus manufactures a wide range of Heater Block Inserts to fit a wide range of machines from OEMs such as K&S, ASM, Shinkawa and more.

Features

  • Suitable for use in a wide range of Wirebonding machines
  • Die pad cavities are machined to ensure exacting position tolerances relative to your leadframe or substrate
  • Contact surfaces and datums of our Heat Block Insert are precision machined for superior flatness to ensure firm workholding of the leadframe or substrate
  • Wide variety of die pad cavity designs like Flat, Angle, Upper Bias, Lower Bias and other customized designs to resolve issues like Non-Stick On Pad (NSOP), die crack and missing wires
  • Materials for our Heat Block Inserts are selected with great care for their excellent heat transfer properties that delivers uniform heat distribution on the contact surfaces of the leadframe or substrate

Benefits

  • Our Heat Block Inserts are designed and manufactured for a perfect fit to your specific application and equipment
  • Plug-and-Play installation that reduces waste and minimizes set up time
  • Precision controlled flatness on the pad cavity and top surface of the heater plate ensures a smooth and productive Wirebonding process
  • Wealth of experience in the requirements for different types of packages
  • In depth understanding of the benefits and limitations of various Wirebond equipment allows us to design the best tool for your particular application
