1. Gịnị mere ihe a na-ere ere ji dị mkpa ka a kpoo ọkụ?
A na-echekwa tapawa solder na mpaghara refrjiraeto (5-10 Celsius), site na refrjiraeto, a ga-ewepụ ya na ụlọ ọrụ SMT na gburugburu ebe obibi okpomọkụ na-ekwekọghị ekwekọ, ma ọ bụrụ na emeghere ya ozugbo iji, site na kọntaktị okpomọkụ na-ekwekọghị ekwekọ, elu nke tapawa solder. ga-arapara na uzuoku mmiri, ma ọ bụrụ na ọ ga-agbanyeghachi ihe na-ere ọkụ dị elu, nwere ike ịpụta tin gbawara agbawa, na-ebute àgwà ọjọọ nke tin beads.Ya mere, tapawa solder ewepụtara na refrjiraeto na-adịkarị mma ịlaghachi na okpomọkụ 2-4H.
2. Gịnị mere a ga-eji kpalie tapawa solder?
Solder tapawa etinye na refrjiraeto, n'ihi na dị iche iche nke solder mado, enịm ruo ogologo oge, ihe dị iche iche nke solder mado ga-apụta layered onu, n'ihi ya, i kwesịrị ịkpali (na-akpali akpali n'otu ụzọ 20-30 tụgharịa. nwere ike), ma ọ bụrụ na ọ bụghị kpaliri ozugbo na, mgbe ahụ dị iche iche mmiri nke solder mado na-adịghị agwakọta, enweghị ike igwu ojiji nke solder mado onwe ya.
Ihe mere e ji edebe ihe ngbochi na friji kama ịnọ na saịtị ahụ ozugbo bụ na tapawa solder nwere ihe mgbaze na rosin, nke ga-ekupụ ma ọ bụrụ na etinye ya ozugbo na ebe kwesịrị ekwesị, si otú a na-eme ka ikuku kpoo.
