Product description

  Laser Trimming System

  LTR Series laser trimming system is the key equipment in the production line of chip resistor.It relates to the technical fields of optics , precision mechanism , computer control, high speed &high precision measurement, etc. It use the high energy pulse laser to focus very small beam spot ( about several ten micro meters ) on the material of the chip resistor, which make the material heat up, melt and gasify. The beam spot scan a graph by dual-galvanometers and vary the conductive length and area of the chip resistor, which vary the resistor's value.

  There are five series according to the application field: (1)LTR420D, thick film chip resistor;

  (2)LTR420E, small size chip resistor(0201,01005);(3)LTR420F, low ohm chip resistor;

  (4)LTR530, thin film chip resistor;(5)LTR-FC, functional circuits.

  LTR Series laser trimming system is the honor product of the CCGH Company. It has been developed 20 years. With complete independent intellectual property rights and good market reputation. Equipments occupy the main domestic market and customers throughout the major Taiwan resistance manufactures and exported to Japan, Thailand, Philippines, Malaysia and other countries. The world's top five chip resistance manufactures are using CCGH's laser trimming system.
