1.Gịnị bụ nzube nke plated ọkara oghere?

Ọ nwere ike ịba uru idowe oghere plated (PTH) na nsọtụ osisi.Dịka ọmụmaatụ mgbe ịchọrọ ịre PCB abụọ n'otu n'otu n'akụkụ 90° ma ọ bụ mgbe ị na-ere PCB na mkpuchi ọla.

2.Gịnị ngwaahịa ọ na-ejikarị eme ihe?

3.PCB mmepụta usoro maka plated ọkara oghere

Ngwunye-ekpu site na oghere (PTH) - panel plating - image transfer - pattern plating -pth half hole- striping - etching - solder mask - silkscreen - ọgwụgwọ elu.

4.What size maka PTH ọkara oghere dị mkpa?

1. Dayameta ≥0.6MM;

2.The anya n'etiti onu onu ≥0.6MM;

3. Obosara nke mgbanaka etching chọrọ 0.25mm;

5.Gịnị mere ọ chọrọ mmezi ụgwọ maka pth ọkara oghere PCB?

Ọkara oghere bụ usoro pụrụ iche.Iji hụ na e nwere ọla kọpa n'ime oghere ahụ, ọ ga-ebu ụzọ gwerie ya tupu ịtinye usoro ọla kọpa.PCB ọkara oghere izugbe dị obere, yabụ ọnụ ahịa ya dị oke ọnụ karịa PCB nkịtị.
