Printed circuit board RF PCBs

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. 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 Hybrid Surface finish: Imm-Sn, Imm-Ag, OSP, ENIG
