PCB dhizaini uye maitiro ekugadzira ane akawanda anosvika makumi maviri maitiro,murombo tinpabhodhi redunhu rinogona kutungamirira kune zvakadai semutsara sandhole, wire collapse, line imbwa mazino, dunhu rakazaruka, mutsara jecha gomba mutsara; Pore ​​mhangura nhete yakakomba gomba pasina mhangura; Kana gomba mhangura yakaonda yakakomba, gomba racho mhangura pasina mhangura; Detin haina kuchena (kudzoka tin nguva kuchakanganisa unhani detin haina kuchena) uye mamwe matambudziko unhu, saka kusangana murombo tin kazhinji zvinoreva kuti kudiwa re-weld kana kunyange kutambisa yapfuura basa, vanofanira remade. Naizvozvo, muindasitiri yePCB, zvakakosha kuti unzwisise zvinokonzeresa matani asina kunaka

Kuonekwa kwemarata asina kunaka kunowanzoenderana nekuchena kwePCB isina chinhu bhodhi pamusoro. Kana pasina kusvibiswa, pachange pasina marata asina kunaka. Chechipiri, solder pachayo irombo, tembiricha uye zvichingodaro. Zvadaro bhodhi redunhu rakadhindwa rinonyanya kuratidzwa mune zvinotevera pfungwa:

1. Iko kune tsvina yakasvibiswa mumucheka weplate, kana kune zvimedu zvekukuya zvakasara pamusoro pemutsara panguva yekugadzirwa kwe substrate.

2. Bhodhi rine girizi, tsvina nezvimwe zvakasiyana-siyana, kana pane silicone mafuta akasara.

3. Iyo yeplate yepamusoro ine pepa remagetsi patin, iyo plate surface coating ine particle tsvina.

4. Yakakwirira inogona kupfekedzwa yakakasharara, pane ndiro inopisa chiitiko, plate yepasi sheet haigone kuve pamarata..

5. Iyo tin surface oxidation uye mhangura yemhangura yakasvibiswa ye substrate kana zvikamu zvakakomba.

6. Rumwe rutivi rwekuputira rwakakwana, rumwe rutivi rwekuputira rwakaipa, yakaderera inogona gomba divi rine pachena yakajeka kumucheto phenomenon.

7. Yakaderera inogona maburi ane pachena inopenya kumucheto chiitiko, yakakwira inogona kukoira yakakasharara, pane ndiro inopisa chiitiko.

8. Iyo welding process haina kuvimbisa tembiricha yakakwana kana nguva, kana kushandiswa kwakaringana kwekuyerera

9. Yakaderera inokwanisa nzvimbo yakakura haigone kuiswa tinned, bhodhi repamusoro rine zvishoma dema dzvuku kana tsvuku, rimwe divi rejasi rakakwana, rimwe divi rejasi rakashata.
