1. Ihe e ji eme brazing
(1) E gosiri ike njikọ nke ọtụtụ ihe eji eme ihe maka brazing ọla kọpa na ọla kọpa na tebụl 10.
Tebụl 10 ike nke njikọ ọla kọpa na ọla kọpa
Mgbe a na-eji ihe e ji agbaze ọla kọpa na tin lead solder, a pụrụ ịhọrọ ihe na-anaghị emebi emebi dịka ihe ngwọta mmanya rosin ma ọ bụ ihe na-arụ ọrụ rosin na ihe ngwọta mmiri zncl2+nh4cl. A pụkwara iji nke ikpeazụ mee ihe maka ihe nkwado ọla kọpa, ọla kọpa na beryllium bronze. Mgbe a na-agbaze ọla kọpa aluminom, ọla kọpa aluminom na ọla kọpa silicon, ihe nkwado ọla kọpa nwere ike ịbụ ihe ngwọta zinc chloride hydrochloric acid. Mgbe a na-agbaze ọla kọpa ọcha manganese, ihe na-enye ọgwụ nwere ike ịbụ ihe ngwọta phosphoric acid. A pụrụ iji ihe ngwọta mmiri zinc chloride dị ka ihe nkwado mmiri mgbe a na-agbaze ọla kọpa, a pụkwara iji fs205 flux mgbe a na-agbaze ọla kọpa dabere na cadmium.
(2) Mgbe a na-eji ọla kọpa eme ihe na brazing filler metals na fluxes, a pụrụ iji ọla kọpa eme ihe na ọla kọpa eme ihe na ọla kọpa eme ihe. Solder dabere na ọlaọcha bụ solder siri ike a na-ejikarị eme ihe n'ihi na ọ na-agbaze nke ọma, ọ na-arụ ọrụ nke ọma, ezigbo ihe onwunwe mechanical, eletriki na okpomọkụ. Maka ọrụ ahụ chọrọ nnukwu conductivity, a ga-ahọrọ solder b-ag70cuzn nwere nnukwu ọlaọcha. Maka brazing vacuum ma ọ bụ brazing na ikuku nchekwa, a ga-ahọrọ b-ag50cu, b-ag60cusn na ihe brazing ndị ọzọ na-enweghị ihe ndị na-agbanwe agbanwe. A ga-ahọrọ ọla brazing nwere obere ọlaọcha dị ọnụ ala, nwere oke okpomọkụ na ike adịghị mma nke njikọ brazed. A na-ejikarị ha eme ihe maka brazing ọla kọpa na ọla kọpa eme ihe na obere ihe achọrọ. A na-eji ọla kọpa eme ihe na ọla kọpa eme ihe naanị maka brazing ọla kọpa na ọla kọpa eme ihe. N'ime ha, b-cu93p nwere ezigbo fluidity ma ejiri ya mee ihe maka akụkụ brazing na-enweghị oke ibu na Electromechanical, ngwa na ụlọ ọrụ mmepụta ihe. Oghere kachasị mma bụ 0.003 ~ 0.005mm. Ọla ọla kọpa phosphorus ọlaọcha nke e ji eme ihe mkpuchi ọla kọpa (dịka b-cu70pag) nwere ike na ike karịa ọla kọpa phosphorus brazing filler. A na-ejikarị ha eme ihe maka njikọ eletriki nwere oke ike conductivity. Tebụl 11 na-egosi njikọ nke ọtụtụ ihe brazing a na-ejikarị eme ihe maka brazing ọla kọpa na ọla kọpa.
Tebụl 11 Njirimara nke njikọ ọla kọpa na ọla kọpa
