Ihame: Filime ngenda ikorwa hejuru yumuringa winama yumuzunguruko, irinda neza ubuso bwumurima mushya, kandi irashobora kandi gukumira okiside no kwanduza ubushyuhe bwo hejuru. OSP Filime ya Filime isanzwe igenzurwa na microne 0.2-0.5.

1. Inzira itemba: Gukaraba → Gukaraba Amazi → Gukaraba Amazi Gukaraba → Gukaraba Amazi Gukaraba Amazi

2. Ubwoko bwibikoresho bya OSP: Rosin, Igikorwa gikora na Azole. Ibikoresho bya OSP bikoreshwa na Shenzhen United On United bikoreshwa cyane Azole OSPS.

Ni ubuhe buryo bwo kuvura hejuru bw'ubuvuzi bwa PCB?

3. Ibiranga: Igorofa nziza, nta IMC yashizweho hagati ya firime ya osp hamwe numuringa winama yumuzunguruko hamwe nikoranabuhanga rito. PCB igaragaza ko Yoko y'Ubutegetsi isaba amakosa: Gusiba bigaragara biragoye, ntibikwiriye kubagurisha benshi (muri rusange bisaba inshuro eshatu); ② ESP EXCIL ISOMO RIROSHEJE GUKURIKIRA; Gukoresha ibidukikije bisabwa; Igihe cyo kubika ni gito.

4. Uburyo bwo kubika nigihe: amezi 6 mu gupakira vacuum (ubushyuhe 15-35 ℃, ubushuhe Rh 6≤60%).

5. Ibisabwa ku rubuga rwa SMT: ① Inama Nkuru y'umuzunguruko igomba kuba yarakomeje ku bushyuhe bwo hasi n'ubushuhe buke (ubushyuhe bwaho butangira mu masaha 48 nyuma yo gupakurura pake ya OSP; ② Birasabwa kubikoresha mu masaha 48 nyuma yigice kimwe kirangiye, kandi birasabwa kubikiza mubushyuhe buke, aho kubirukana ubushyuhe;
