1. Mhepo inopisa yemhepo inoiswa pamusoro pePCB yakanyungudutswa tin inotungamira murindiri uye yakadzvanywa yakamanikidzwa kumhepo (kuputika flat) maitiro. Kugadzira kuti iite oxidation inodzivirira kubhururuka kunogona kupa zvakanaka. Muchengeti wemhepo inopisa uye mhangura inoumba mhangura-sikkim yakaomeswa pamutambo, ine gobvu dzinosvika 1 kusvika ku2MIL.
2. Organic Solorability Preservative (OSP) nekukura kwemakemikari kuunganidza organc coating pamhangura yakachena isina chinhu. Iyi PCB Multlayer firimu ine kugona kuramba oxidation, kupisa kuvhunduka, uye kunyorova kuchengetedza iyo mhangura yemhangura kubva kumarara (oxidation kana sulfutization, nezvimwewo) pasi pezvakajairwa. Panguva imwecheteyo, pakutevedzana kwakapetwa tembiricha, inotyisa flux inokurumidza kubviswa nekukurumidza.

3. Kwenguva yakareba, kusiyana neOsp, iyo inongoshandiswa chete sechikepe cheRustroof, inogona kushandiswa kushandiswa kwenguva refu PCB uye uwane simba rakanaka. Mukuwedzera, iyo ine kutsigira kwezvakatipoteredza kuti mamwe maitiro ekurapa ekurapa haana.

Kufumurwa kune kupisa, kwakasvibiswa uye kusvibiswa nharaunda kuchiri kupa zvakanaka zvemagetsi maitiro uye hutano hwakanaka, asi tarnish. Nekuti hapana Nickl pasi peSilver Layer, sirivheri yakagadzirirwa haina simba rese retsika reiyo nickel isina / kunyudzwa kwegoridhe.

5.Kutadzira kweiko pamusoro pePCB multlayer bhodhi yakavezwa neiyo Nicker Goridhe, kutanga neyenzi yeNickel uyezve negoridhe. Chinangwa chikuru cheNickel plating ndeyekudzivirira kusiyana pakati pegoridhe uye ndarira. Kune marudzi maviri egoridhe-rakapfava. Goridhe yakapfava inonyanya kushandiswa chiping pairipo goridhe mutsara; Goridhe rakaoma rinonyanya kushandiswa kune isina-welder magetsi emagetsi kusawirirana.

6. PCB yakasanganiswa kurapwa tekinoroji inosarudza nzira mbiri dzekurapa, nzira dzakajairika, Nickel Plongation, Nickel Planing Goridhe Inopisa Mhepo, inorema Nickel uye Goridhe Inopisa Mhepo. Kunyangwe shanduko yePCB multillayer yemhando yekurapa haina kukosha uye inoita senge iri kure, inofanira kucherechedzwa kuti nguva yakareba yekushanduka inononoka ichaunza shanduko huru. Nekuwedzera kwekuwedzera kwekudzivirirwa kwezvakatipoteredza, tekinoroji yekurapa yePCB inosungirwa kuchinja zvakanyanya mune ramangwana.
