HDI Process PCB Board HCT Withstand Current Test Machine Ⅰ Introduction High Density Interconnections HDI board refers to the circuit board produced by high-density
micro-wiring and tiny through-hole technology. It is a relatively
new technology developed in the PCB industry at the end of the 20th
century. Compared with traditional PCB, laser drilling technology
(also known as laser board) is used to drill smaller holes,
narrower lines and substantially reduced pads. More lines can be
distributed within all unit area. High-density interconnection
results from this, and the emergence of HDI technology ADAPTS to
and promotes the development of PCB industry, and at the same time
requires higher production and testing of PCB board. Ⅱ HCT Testing purposes: Current resistance test is a test method to test the hole
interconnection reliability of printed circuit board products. At
present, various manufacturers need printed board suppliers to
import HCT test. Current resistance test is to apply a certain DC
current to a specially designed hole chain, and continue for a
period of time. The current generates joule heat on the hole chain,
and the heat is transferred to the base material near the hole
chain. When the base material is heated, the expansion stress in
the Z direction leads to the fracture of the blind hole, so as to
detect the reliable interconnection performance of the hole chain. Ⅲ Instrument accuracy and parameters: 1.
