Iibhodi zesekethe eprintiweyo RED solder imaski imingxuma castela

Iinkqubo zemingxunya enesiqingatha ezicandiweyo zezi:
1. Yenza umngxuma wesiqingatha secala kunye nesixhobo sokusika esine-V kabini.

2. I-drill yesibini yongeza imingxuma yesikhokelo kwicala lomngxuma, isusa ulusu lobhedu kwangaphambili, inciphisa i-burrs, kwaye isebenzisa ii-groove cutters endaweni ye-drills ukuze kulungiswe isantya kunye nokulahla isantya.

3. Gxininisa ubhedu kwi-electroplate i-substrate, ukwenzela ukuba umaleko wobhedu ufakwe kwi-electroplated eludongeni lomngxuma womngxuma ojikelezayo kumda webhodi.

4. Ukuveliswa kwesekethe yangaphandle yomaleko emva kokulanyiswa, ukuvezwa, kunye nophuhliso lwe-substrate ngokulandelelana, i-substrate ixhomekeke kwi-plating yobhedu yesibini kunye ne-tin plating, ukwenzela ukuba umaleko wobhedu kudonga lomngxuma womngxuma ojikelezayo ibhodi iyaqina kwaye umaleko wobhedu ugutyungelwe ngumaleko we-tin wokumelana nokubola;

5. Ukwenza umngxuma wesiqingatha unqumle umngxuma ojikelezayo kumda webhodi kwisiqingatha ukwenza umngxuma;

6. Kwisinyathelo sokususa ifilimu, ifilimu ye-anti-electroplating ecinezelekileyo ngexesha lenkqubo yokucofa ifilimu iyasuswa;

7. Ukubethelwa kwe-substrate kufakwe, kwaye ubhedu oluvezwayo kuluhlu lwangaphandle lwe-substrate lususwe ngokucofa;

8. I-tin ehlutha i-substrate ihluthwe i-tin, ukwenzela ukuba i-tin eludongeni lwe-half-hole inokususwa, kunye nobhedu oluseludongeni lwe-half-hole lubonakaliswe.

9. Emva kokwenza, sebenzisa iteyiphu ebomvu ukuncamathelisa iibhodi zeyunithi kunye, kwaye ususe iibhula ngomgca we-alkaline etching.

10. Emva kobhedu lwesibini lobhedu kunye nokufakwa kwe-tin kwi-substrate, umngxuma ojikelezayo osekupheleni kwebhodi unqunyulwe kwisiqingatha ukuze wenze isiqingatha somngxuma, kuba ubhedu bodonga lomngxuma lugutyungelwe ngumaleko wetin, kunye ne-tin. umaleko ubhedu eludongeni umngxuma ngokupheleleyo kunye umaleko ubhedu umaleko wangaphandle substrate Connection, ebandakanya amandla bonding olomeleleyo, unako ukuthintela ngempumelelo umaleko ubhedu eludongeni umngxuma ukuba itsalwe okanye ubhedu warping xa ukusika;

11. Emva kokuba ukwakhiwa komngxuma wesiqingatha kugqityiwe, ifilimu iyasuswa kwaye igxininiswe, ukwenzela ukuba ubuso bobhedu bungabi yi-oxidized, ngokufanelekileyo ukuphepha ukwenzeka kobhedu olushiyekileyo okanye isiphaluka esifutshane, kunye nokuphucula izinga lesivuno sesiqingatha se-metallized. -umngxuma PCB ibhodi yesekethe.
