Applying of Thin Layer Resistors in Multilayer Printed Circuit Boards

摘要

In the paper there are presented the theory and aspects of choosing of resistors construction and technology of embedding thin-layer resistors inside multilayer PCBs (Printed Circuit Boards). The two kind of Ohmega-Play~® laminates (1R25/1 25 Ω/□ and 1A100/1 100 Ω/□) were investigated. The results of investigations of applying embedded resistors also are presented. The experiments were focused on achieving the resistances from typical row E12. The deviation of electrical resistance of manufactured resistors not exceed the ranges ± 8% and —12% to +2% with using of RCM materials type 1R25/1 25 Ω/□ and 1A100/1 100 Ω/□ respectively. The presented results of investigations determine the first part of work made in PCB manufacturing field in Tele and Radio Research Institute.
