Multilayer PCB liboto potoloho ka kakaretso sebelisoa ka thepa ea puisano, thepa ea bongaka, taolo ya indasteri, tshireletso, likoloi likoloi, lifofane, lik'homphieutha peripheral masimo; E le "matla a mantlha a mantlha" mafapheng ana, ka keketseho e tsoelang pele ea mesebetsi ea sehlahisoa, mela e mengata e teteaneng, litlhoko tse tsamaellanang tsa 'maraka tsa boleng ba boto le tsona li ntse li phahama le ho feta, le tlhoko ea bareki ea mahareng le a holimo. Liboto tsa potoloho tsa TG li lula li eketseha.

Ea bobeli, ho khetheha ka liboto tse ngata tsa lera PCB potoloho

Tloaelehileng PCB boto tla ba le deformation le mathata a mang ka mocheso phahameng, ha litšobotsi tsa mechine le motlakase le tsona li ka fokotseha haholo, ho fokotsa bophelo ba tšebeletso ea sehlahisoa. Tšimo ea ts'ebeliso ea boto ea PCB e nang le likarolo tse ngata hangata e fumaneha indastering ea theknoloji e phahameng, e hlokang ka ho toba hore boto e be le botsitso bo phahameng, khanyetso e phahameng ea lik'hemik'hale, 'me e ka mamella mocheso o phahameng, mongobo o phahameng joalo-joalo.

Ka hona, tlhahiso ea mapolanka a PCB a mangata a sebelisa bonyane lipoleiti tsa TG150, e le ho etsa bonnete ba hore boto ea potoloho e fokotsoa ke lintlha tse ka ntle nakong ea kopo le ho lelefatsa bophelo ba tšebeletso ea sehlahisoa.

Ntlha ea boraro, botsitso ba mofuta oa poleiti ea TG e phahameng le ho tšepahala ho phahameng

TG boleng ke eng?

TG boleng: TG ke mocheso phahameng ka ho fetisisa eo lakane e lula e le thata, 'me TG boleng e bua ka mocheso oo polymer amorphous (hape ho akarelletsa le karolo ea amorphous ea crystalline polymer) liphetoho ho tloha boemong ba khalase ho boemo bo phahameng ba rekere (rabara). mmuso).

Boleng ba TG ke mocheso oa bohlokoa oo substrate e qhibilihang ho tloha ho tiileng ho isa ho metsi a rubbery.

Boemo ba boleng ba TG bo amana ka ho toba le botsitso le botšepehi ba lihlahisoa tsa PCB, 'me boleng ba TG bo phahameng ba boto, bo matlafatsa botsitso le ho tšepahala.

Letlapa le phahameng la TG le na le melemo e latelang:

1) Ho hanyetsa mocheso o phahameng, ho ka fokotsang ho phaphamala ha liphahlo tsa PCB nakong ea ho qhibiliha ho chesang ha infrared, welding le ho makala ha mocheso.

2) Coefficient e tlase ea ho eketsa mocheso (CTE e tlase) e ka fokotsa ho phatloha ho bakoang ke maemo a mocheso, 'me ea fokotsa ho robeha ha koporo k'honeng ea lesoba le bakoang ke ho atolosoa ha mocheso, haholo-holo ka mapolanka a PCB a nang le likarolo tse robeli kapa ho feta, ts'ebetso ea ho phunyeletsa ka masoba. e betere ho feta ea liboto tsa PCB tse nang le litekanyetso tsa TG tse akaretsang.

3) E na le khanyetso e ntle ea lik'hemik'hale, e le hore boto ea PCB e ka kolobisoa ts'ebetsong ea phekolo ea metsi le litharollo tse ngata tsa lik'hemik'hale, ts'ebetso ea eona e ntse e tiile.
