PCBA daahan waafaqsan socodka habka buufinta

Sida laga soo xigtay macaamiishu waxay u baahan yihiin, Cirket sidoo kale waxay leeyihiin adeeg daahan conformal ah.PCBA daahan conformal waxay leedahay dahaarka aad u fiican, qoyaan-caddayn, daadinta-caddayn, shoogga-caddayn, boodhka-cadayn, daxalka-caddayn, ka-hortagga gabowga, caariyaysi-cadayn, ka-hortagga qayb dabcinta iyo dahaarka guryaha iska caabinta corona, kaas oo kordhin kara wakhtiga kaydinta PCBA. Cirket had iyo jeer waxay isticmaashaa buufinta taas oo sidoo kale ah habka daahan ee inta badan loo isticmaalo warshadaha.

Cirket PCBA daahan waafaqsan socodka habka buufinta

1. Qalabka loo baahan yahay

Rinjiga dahaarka ah ee caadiga ah, sanduuqa rinjiga, galoofyada caagga ah, maaskaro ama maaskaro gaaska, buraash, cajalad dhejis ah, maroojiyeyaal, qalabka hawo-qaadista, weel qalajinta iyo foornada.

2. Tallaabooyinka buufinta

Rinjiyeynta dhinac → qallajin oogada → rinjiyeynta dhinaca B → daawaynta heerkulka qolka hoostiisa

3. Shuruudaha dahaarka

(1) Nadiifi oo qalaji looxa si aad uga saarto qoyaanka iyo biyaha PCBA-ga. Boodhka, qoyaanka iyo saliidda dusha PCBA-da ee la dahaarinayo waa in marka hore meesha laga saaraa si dahaarka uu si buuxda u sameeyo saamayntiisa difaaceed. Nadiifinta si fiican waxay xaqiijin kartaa in haraaga daxalka gabi ahaanba meesha laga saaro oo daahan qaabaysan uu si fiican ugu dheggan yahay dusha sare ee guddiga wareegga. Xaaladaha dubista: 60 ° C, 10-20 daqiiqo. Saamaynta ugu fiican ee daahan ayaa ah buufinta marka looxa uu kulul yahay ka dib marka laga soo saaro foornada.

(2) Marka la cadaynayo daahan conformal , aagga daahan waa in ay ka weyn tahay meesha ay ku jiraan qaybaha si loo hubiyo in dhammaan qaybaha iyo suufka la daboolay.

(3) Marka la cadaynayo daahan conformal , looxa wareegga waa in la dhigo sida siman sida ugu macquulsan. Waa inaysan jirin wax dhibicyo ah ka dib cadayashada. Dahaarka waa inuu ahaadaa mid siman oo waa inaysan jirin qaybo bannaan. Dhumucdiisu waa inay u dhaxaysaa 0.1-0.3mm.

(4) Ka hor inta aan la cadaynayn ama buufin daahan aan toos ahayn, shaqaalaha Cirket waxay xaqiijiyaan in daahan la milmay si buuxda loo walaaqay oo looga tagay 2 saacadood ka hor inta aan la cadaynayn ama buufin. Isticmaal buraash faybar dabiici ah oo tayo sare leh si aad si tartiib ah u cadaydo oo aad u dhex geliso heerkulka qolka. Haddii la isticmaalayo mishiinka , viscosity ee daahan waa in la cabbiraa (iyadoo la isticmaalayo a viscosity tester ama koobka socodka) iyo viscosity waxaa lagu hagaajin karaa dareere ah.

Qaybaha looxa wareegga waa in si toos ah loogu dhex geliyo haanta dahaarka ah ugu yaraan i daqiqo ilaa ay goobooyinku ka baaba'aan oo si tartiib ah meesha looga saaro. Fadlan ogow in xiriiriyayaasha aan la quusin haddii aan si taxadar leh loo daboolin . Filim labis ah ayaa ka samaysan doona dusha sare ee looxa wareegga. Inta badan haraaga rinjiga waa in ay dib uga soo noqdaan guddiga wareegga ilaa mashiinka wax lagu duubo. TFCF waxay leedahay shuruudo daahan oo kala duwan. Xawaaraha lagu riixo guddiga wareegga ama qaybaha waa inaysan noqon mid aad u degdega si looga fogaado xumbo xad-dhaaf ah.

(6) Haddii uu jiro qolof dusha sare ah marka la isticmaalayo mar kale ka dib markaad wax ku shubto, ka saar maqaarka oo sii wad isticmaalka.

(7) Ka dib markaad cadaydo, dhig looxa wareegga si siman u dul saar garabka una diyaari daawaynta. Waa lagama maarmaan in la kululeeyo si loo dardargeliyo daaweynta dahaarka. Haddii dusha sare ee dahaarka uu yahay mid aan sinnayn ama ay ku jiraan xumbo, waa in lagu dhejiyaa heerkulka qolka muddo dheer ka hor inta aan lagu daweyn foorno heerkul sare ah si ay ugu oggolaato dareeraha inuu soo baxo.

Ka taxadaritaan

1. Inta lagu jiro habka buufinta, qaybo ka mid ah lama buufin karo, sida: dusha sare ee kuleylka kuleylka ama qaybaha kulaylka, iska caabiyeyaasha korontada, diodes power, resistors cement, dip switches, resistors adaptable, buzzers, battery holders, fiyuus haystayaasha tuubooyinka), kuwa haysta IC, furayaasha taabashada, iwm.

2. Waa mamnuuc in lagu shubo rinjiga saddexda aan caddayn ee soo hadhay weelka asalka ah ee kaydinta. Waa in si gaar ah loo kaydiyaa oo la xidhaa.

3. Haddii qolka shaqada ama qolka kaydinta uu xiran yahay waqti dheer (in ka badan 12 saacadood), hawo sii 15 daqiiqo ka hor inta aanad gelin.

4. Haddii ay si lama filaan ah ugu firdhiso muraayadaha, fadlan isla markiiba fur daboolka sare iyo hoose oo ku raaci biyo socda ama cusbo, ka dibna raadso daaweyn.
