Many electronic applications are seeing a need for increasingly faster frequencies. As frequency increases, the margin for error and/or deviations in the pcb is significantly reduced. The use of high frequency material like PTFE substrates, blind vias and tightly controlled etch tolerances are required to achieve such high frequencies.
Kinwong capabilities are as follows:
Raw Material: hydrocarbon + ceramic filler, Hydrocarbon+fiberglass, PPO+Filler, PTFE + ceramic filler, PTFE + fiberglass etc.
Precise etching tolerance of +/-18um for vital copper patterns.
LDI, higher conformity to the original design
Layer registration tolerance: +/-4mil
Buried via/ blind via/ micro-via
Surface finish: Imm-Sn, Imm-Ag, OSP, ENIG
