Bakeng sa ho netefatsa boleng ba aluminium substrate PCB , boleng bo phahameng ba solder bo lokela ho sebelisoa ts'ebetsong ea tlhahiso ho ntlafatsa ts'ebetso ea Welding le ho thibela warpage le defect.So, lisosa tsa likotlo tsa welding tsa PCB ho aluminium substrate ke life? Latela litsebi litsebi aluminium PCB ba Yongmingsheng ho utloisisa.
1. The weldability lesoba la boto oa potoloho na le tšusumetso boleng boleng tjheseletsa.
Ka lebaka la ho se rekisoe hantle ha mokoti oa boto ea potoloho, ho tla ba le liphoso tsa ho tjheseletsa, tse tla ama likarolo tsa likarolo tsa potoloho, tse bakang likarolo le karolo e kahare ea ho se tsitse ha mohala, ho fellang ka ts'ebetsong ea ho hloleha ha potoloho .
2. Mathata a ho tjheseletsa a bakoang ke ho kotana.
Boto ea potoloho le likarolo li tla ohla nakong ea ho tjheseletsa, 'me khatello ea maikutlo le ho fetoha li tla lebisa ho tjheseletsa, potoloho e khuts'oane le liphoso tse ling. Ho loana hangata ho bakoa ke tekano ea mocheso lipakeng tsa likarolo tse kaholimo le tse tlase tsa boto ea potoloho. polypropylene, boto e loha ka lebaka la boima ba eona.
3. Moralo oa boto ea potoloho o ama boleng ba tjheseletsa.
Ho tloha ponong ea moralo, boholo ba boto ea potoloho bo boholo haholo, leha ts'ehetso e le bonolo ho e laola, empa mohala o hatisitsoeng o molelele, impedance ea eketseha, litjeo lia eketseha; Boholo bo nyane haholo, mocheso oa mocheso oa fokotseha, ho tjheseletsa ha ho bonolo ho li laola, 'me ho sitisoa ka bobeli ha mela e haufi ho bonolo ho etsahala.
Kahoo moralo oa boto ea PCB o tlameha ho ntlafatsoa:
A. E fokotsa likhokahano lipakeng tsa likarolo tse phahameng tsa maqhubu le ho fokotsa tšitiso ea motlakase.
B. Bakeng sa likarolo tse boima, li lokise ka libakete ebe u li kopanya.
C. Lisebelisoa tsa mocheso li lokela ho nkuoa e le ho chesa ha mocheso, likarolo tsa mocheso li lokela ho ba hole le mohloli oa mocheso.
Lisebelisoa li hlophisitsoe ka mokhoa o ts'oanang ka hohle kamoo ho ka khonehang, e seng e ntle feela, empa hape e bonolo ho o chesa ebile e loketse tlhahiso ea bongata. Moralo o motle bakeng sa boto ea potoloho ke khutlonne ea 4∶3. ka tšohanyetso 'me u qobe ho sebelisa libaka tse kholo tsa foil ea koporo.
Tse kaholimo ke sesosa sa liphoso tsa welding ho PCB ea substrate ea aluminium. Re ts'epa hore e ka ba thuso ho uena.Re tsoa ho mofani oa thepa ea China ea aluminium substrate - Yongmingsheng Electronics, re amohela ho botsa!
