Nguva Dzinoshanda: Inofungidzirwa kuti inenge 25% -30% yePCBS parizvino inoshandisa iyo OSP maitiro, uye chikamu chave chiri kusimuka (zvingangoita kuti iyo OSP maitiro ikozvino yapfuura iyo Spray Tin uye Spors kutanga). Iyo OSP maitiro inogona kushandiswa pane yakaderera-tech PCBS kana High-tech PCBs, yakadai seyisiti-yakagadzirirwa TV PCBS uye yakakwira-density chip ekutakura mabhodhi. For BGA, kune vakawandaOspzvikumbiro. Kana PCB isina nzvimbo yekubatanidza inoshanda inodiwa kana yekuchengetedza nguva inotora, iyo Osp maitiro ichave yakakodzera kwazvo kurapwa kwekurapa maitiro.

Kubatsira kukuru: Izvo zvine zvese zvakanakira bhodhi yemhete, uye bhodhi rakapera (mwedzi mitatu) inogona zvakare kugariswa, asi kazhinji kamwe chete.

Zvinokuvadza: Kukanganiswa neAcid uye humidity. Kana ichishandiswa sekondari inopazwa, inoda kupedzwa mukati menguva yakati. Kazhinji, mhedzisiro yeiyo yechipiri inopenya inotengeserana ichava murombo. Kana nguva yekuchengetera ichipfuura mwedzi mitatu, inofanira kutengerwa. Shandisa mukati memaawa makumi maviri nemana mushure mekuvhura package. OSP inzvimbo inosimbisa, saka iyo nguva yebvunzo inofanira kudhindwa nemutengesi pasita kubvisa iyo yekutanga Opt Layer yekubata iyo PIN point yekuongororwa kwemagetsi.

Nzira: Pane iyo yakachena isina bure yemhangura yemhangura, denderedzwa re organic firimu rakakura nenzira yemakemikari. Iyi firimu ine anti-oxidation, inovhunduka, unyoro, uye inoshandiswa kuchengetedza iyo mhangura yemhangura kubva mukubvarura (oxidation kana vulcanization, nezvimwewo nharaunda; Panguva imwecheteyo, inofanira kubatsira nyore nyore mukudziya kwakazara kwekushisa kweWelding. Flux inokurumidza kubviswa kuti ichitengeswa;
