Motheo oa Motheo oa BGA Rework Station

BGA rework stationke lisebelisoa tsa setsebi tse sebelisetsoang ho lokisa likarolo tsa BGA, tse atisang ho sebelisoa indastering ea SMT.Ka mor'a moo, re tla hlahisa molao-motheo oa BGA rework station le ho sekaseka lintlha tsa bohlokoa ho ntlafatsa sekhahla sa tokiso ea BGA.

BGA rework station ka aroloa ka optical counterpoint lokisa tafole le non-optical counterpoint lokisa tafole.Optical counterpoint e bua ka ho lokisoa ha optics nakong ea welding, e ka netefatsang ho nepahala ha ho tsamaisana le welding le ho ntlafatsa sekhahla sa katleho ea welding.Non-optical counterpoint, e etsoang ka pono, ha e nepahale hantle ha e cheselletsa.

Hajoale, mekhoa e meholo ea ho futhumatsa ea BGA rework station e kenyelletsa infrared e felletseng, moea o chesang o felletseng le moea o chesang tse peli le infrared e le 'ngoe.Mekhoa e fapaneng ea ho futhumatsa e na le melemo le melemo e fapaneng.Mokhoa o tloaelehileng oa ho futhumatsa oa BGA rework station naheng ea China hangata ke moea o chesang likarolong tse ka holimo le tse ka tlaase le preheating ea infrared ka tlase, e bitsoang libaka tse tharo tsa mocheso.Lihlooho tse futhumatsang tse ka holimo le tse tlaase li futhumatsoa ke terata e futhumatsang 'me moea o chesang o romelloa ka ntle ka ho phalla ha moea.Preheating e ka tlase e ka aroloa ka tube e khubelu e lefifi ea kantle e futhumatsang, poleiti e futhumatsang ea infrared le poleiti e futhumatsang ea maqhubu a khanya ea infrared.

1. Ho futhumatsa le ho theosa le khanya

Ka ho futhumatsa terata e futhumatsang, moea o chesang o tla fetisetsoa ho likarolo tsa BGA ka nozzle ea moea, ho fihlela sepheo sa ho futhumatsa likarolo tsa BGA, 'me ka moea o ka holimo le o tlase o chesang, o ka thibela boto ea potoloho e sa lekanang ho futhumatsa deformation.

2. Ho futhumatsa ka tlase ho infrared

Ho futhumatsa ha infrared haholo-holo ho phetha karolo ea ho futhumatsa pele, ho tlosa mongobo ka har'a boto ea potoloho le BGA, hape ho ka fokotsa ka katleho phapang ea mocheso pakeng tsa setsi sa ho futhumatsa le se potolohileng, ho fokotsa monyetla oa ho senyeha ha boto ea potoloho.

3. Tšehetso le fixture ea BGA rework station

Karolo ena haholo-holo e tšehetsa le ho lokisa boto ea potoloho 'me e phetha karolo ea bohlokoa ho thibela ho senyeha ha boto.

4. Ho laola mocheso

Ha o qhaqha le ho cheselletsa BGA, ho na le tlhokahalo ea bohlokoa bakeng sa mocheso.Haeba mocheso o phahame haholo, ho bonolo ho chesa likarolo tsa BGA.Ka hona, tafole ea ho lokisa ka kakaretso e laoloa ntle le sesebelisoa, empa e amohela taolo ea PLC le taolo e felletseng ea komporo, e ka laolang mocheso ka nako ea nnete.

Ha u lokisa BGA ka seteishene sa rework, ke haholo-holo ho laola mocheso oa mocheso le ho thibela ho senyeha ha boto ea potoloho.Ke feela ka ho etsa likarolo tsena tse peli hantle moo sekhahla sa katleho ea ho lokisa BGA se ka ntlafatsoang haholo.
