Dị ka usoro, PCB ígwè ntupu nwere ike kere n’ime ndị na -esonụ ụdị:

1, ụgbụ nchara nchara: dị ka aha ya pụtara, a na -eji ahịhịa mpe mpe akwa. Bee oghere n’ime mpempe nchara nke dabara na bọọdụ PCB. Mgbe ahụ, a na -ebipụta mpekere solder na bọọdụ PCB site na ntupu nchara. Mgbe ị na -ebipụta mpe mpe akwa, a na -etinye mpe mpe akwa ahụ n’elu ntupu nchara, wee tinye bọọdụ sekit na ala nke ntupu nchara, wee jiri nchachachachapu mpe mpe akwa na ntupu nchara nha ( A ga -afanye mpe mpe akwa site na ntupu nchara wee kpuchie bọọdụ sekit). Nọgidesie ike na ngwongwo ihe, ịgbado ọkụ nwere ike ịdị n’otu nwere ike ịbụ, ịgbado ọkụ ihe eji eme ya.

2, akwa roba na -acha ọbara ọbara: oghere dị ka nha na ụdị akụkụ ga -emepe n’etiti paịlị abụọ nke ngwa ahụ. Ojiji nke na -ekesa (ikesa bụ iji mkpakọ eme ihe efu, gluu na -acha ọbara ọbara site na isi pụrụ iche na -enye aka na mkpụrụ) gluu uhie site na ntụpọ nchara na bọọdụ PCB. Mgbe ahụ tinye ihe ndị mejupụtara ya, dị ka ngwa yana nkwụsi ike nrachi PCB, pịnye na ihe nkwụnye ihe na-agbakọ ọnụ.

3, ụgbụ nchara usoro okpukpu abụọ: mgbe bọọdụ PCB kwesịrị ịcha mpe mpe mpe akwa, wee chọọ ịcha gluu uhie, mgbe ahụ ịkwesịrị iji ụgbụ nchara abụọ. The abụọ usoro ígwè ntupu na -emi esịnede abụọ ígwè ntupu, otu nkịtị laser ntupu na otu ntupu ntupu. Kedu otu esi achọpụta ojiji nke solder paste steepụ nchara ma ọ bụ uhie gluu steepụ nchara? Buru ụzọ ghọta ma ị ga -ebu ụzọ ete ihe nkedo gbamgbam ma ọ bụ nke na -acha ọbara ọbara. Ọ bụrụ na ọ bụ nke mbụ ahịhịa solder tapawa, mgbe ahụ solder tapawa ígwè ntupu mere nke nkịtị laser ígwè ntupu, red gluu ígwè ntupu mere nke n’ọkwá ígwè ntupu. Ọ bụrụ na ọ bụ nke mbụ na -ete gluu na -acha uhie uhie, mgbe ahụ, a na -eme ụgbụ nchara na -acha uhie uhie ka ọ bụrụ ụgbụ nchara laser nkịtị, na ụgbụ nchara nchara na -eme ka ụgbụ nchara nchara.
