I-PCB design kanye nenqubo yokukhiqiza inezinqubo ezingaba ngu-20,ithini elimpofuebhodini lesifunda kungase kuholele ku-sandhole yomugqa, ukuwa kocingo, amazinyo ezinja zomugqa, isifunda esivulekile, umugqa wesihlabathi somgodi;Imbobo yethusi encane imbobo engathi sina ngaphandle kwethusi;Uma imbobo yethusi mncane sina, imbobo yethusi ngaphandle ithusi;I-Detin ayihlanzekile (izikhathi zokubuyisela ithini zizothinta i-coating detin ayihlanzekile) nezinye izinkinga zekhwalithi, ngakho-ke ukuhlangana kwethini elimpofu ngokuvamile kusho ukuthi isidingo sokushisela kabusha noma ukumosha umsebenzi wangaphambilini, sidinga ukwenziwa kabusha.Ngakho-ke, embonini ye-PCB, kubaluleke kakhulu ukuqonda izimbangela zamathini ampofu

Ukubukeka kwethini elimpofu ngokuvamile kuhlobene nokuhlanzeka kwebhodi elingenalutho le-PCB.Uma kungekho ukungcola, ngeke kube khona ithini elimpofu.Okwesibili, i-solder ngokwayo impofu, izinga lokushisa njalonjalo.Khona-ke ibhodi lesifunda eliphrintiwe liboniswa ngokuyinhloko kumaphuzu alandelayo:

1. Kukhona ukungcola kwezinhlayiyana embotsheni yepuleti, noma kukhona izinhlayiya zokugaya ezisele ebusweni bomugqa ngesikhathi sokukhiqiza i-substrate.

2. Ibhodi elinamafutha, ukungcola nokunye okuhlukile, noma kukhona insalela kawoyela we-silicone

3. Indawo yepuleti ineshidi likagesi ethini, i-plate surface coating inokungcola okuyizinhlayiyana.

4. Ukwemboza okungase kube sezingeni eliphezulu kunzima, kunento yokushiswa kwamapuleti, ishidi elingaphezulu kwepuleti alikwazi ukuba phezu kukathini..

5. I-oxidation ye-tin surface kanye nokuba buthuntu kwendawo yethusi ye-substrate noma izingxenye zibucayi.

6. Olunye uhlangothi lwe-coating luphelele, olunye uhlangothi lwe-coating lubi, uhlangothi lwembobo oluphansi olunamandla lunomkhuba ocacile onqenqemeni.

7. Izimbobo ezingaba eziphansi zibe sobala onqenqemeni isenzeko, high engaba enamathela emangelengele, kukhona ipuleti evuthayo mkhuba.

8. Inqubo ye-welding ayiqinisekisi izinga lokushisa elanele noma isikhathi, noma ukusetshenziswa okufanele kwe-flux

9. Indawo enkulu engase ibe namandla aphansi ayikwazi ukuthayela, ingaphezulu lebhodi linombala omnyama obomvu noma obomvu, uhlangothi olulodwa lwe-coating luphelele, olunye uhlangothi lwe-coating lubi.
