Abstract
The effect of high speed laser trimming on accuracy and stability of thick film resistors
Highlights
The overall subject of high speed laser trimming increases in importance as more emphasis is placed on the manufacture of resistor networks and high volume thick film hybrid circuits
It has been estimated that the laser trimming process is 40% of the cost of processing a thick film resistor network
High speed laser trimming should immediately be distinguished from high throughput
Summary
The overall subject of high speed laser trimming increases in importance as more emphasis is placed on the manufacture of resistor networks and high volume thick film hybrid circuits. We have introduced two important laser trimming parameters- PEAK POWER and PULSE REPETITION RATE. At this point, it is useful to introduce two more laser terms- AVERAGE. The other consists of "X" and "Y" arms activated by directly-coupled voice coil linear actuators The depth of field for these optics is Krypton lamp*
