E 'ngoe-stop Electronic Manufacturing Services, e u thusa ho fumana lihlahisoa tsa hau tsa elektroniki habonolo ho tsoa ho PCB & PCBA

Na boholo ba boto ea potoloho bo botala? Ho na le bohlale bo bongata ho eona

Haeba u botsoa hore na boto ea potoloho ke 'mala ofe, ke lumela hore maikutlo a pele a motho e mong le e mong a tala. Ke 'nete hore boholo ba lihlahisoa tse felileng indastering ea PCB li tala. Empa ka tsoelo-pele ea theknoloji le litlhoko tsa bareki, ho hlahile mebala e sa tšoaneng. Khutlela mohloling, ke hobane'ng ha liboto li le tala haholo? Ha re bue ka eona kajeno!

Karolo e tala e bitsoa solder block. Lisebelisoa tsena ke li-resin le li-pigments, karolo e tala ke li-pigments tse tala, empa ka tsoelo-pele ea theknoloji ea morao-rao, e fetiselitsoe ho mebala e meng e mengata. Ha e fapane le pente e khabisitsoeng. Pele solder e hatisoa ka boto ea potoloho, ho hanyetsa solder ke ho peista le ho phalla. Ka mor’a ho hatisa botong ea potoloho, resine eo ea thatafala ka lebaka la mocheso ’me qetellong ea “fola.” Sepheo sa ho hanyetsa welding ke ho thibela boto ea potoloho ho tloha mongobo, oxidation le lerōle. Sebaka se le seng feela se sa koaheloang ke "solder block" hangata se bitsoa pad mme se sebelisetsoa paste ea solder.

 

Ka kakaretso, re khetha botala hobane ha bo halefise mahlo, 'me ha ho bonolo hore basebetsi ba tlhahiso le tlhokomelo ba shebe PCB nako e telele. Ka moralo, mebala e sebelisoang hangata e mosehla, e ntšo le e khubelu. Mebala e pentiloe holimo ka mor'a hore e etsoe.

 

Lebaka le leng ke hore 'mala o sebelisoang ka tloaelo ke o motala, kahoo fektheri e na le pente e tala e sa sebetseng, kahoo theko ea oli e tlase haholo. Hape ke hobane ha u sebeletsa boto ea PCB, ho bonolo ho khetholla lithapo tse fapaneng ho tloha ho tse tšoeu, ha tse ntšo le tse tšoeu li batla li le thata ho li bona. E le ho khetholla limaraka tsa lihlahisoa tsa eona, fektheri e 'ngoe le e' ngoe e sebelisa mebala e 'meli ho khetholla letoto la maemo a holimo ho tloha letotong le tlaase. Mohlala, Asus, k'hamphani ea boardboard ea komporo, boto e mosehla ke pheletso e tlase, letlapa ke pheletso e phahameng. Rebound ea Yingtai e holimo, 'me boto e tala e tlaase.
