Ngaba ndiyakwazi ukuhlamba okanye ukucoca i-PCB eqinile-eguqukayo? Konke okufuneka ukwazi

Yazisa

xa kuziwa ekugcinweni nasekucoceni, abasebenzisi abaninzi be-PCB abaqinisekanga ukuba iibhodi eziqinileyo-flex ziyakwazi ukuhlanjwa okanye zicocwe ngaphandle kokwenza umonakalo. Kule posi yebhlog, siza kuntywila kwesi sihloko ukuze sikubonelele ngezimvo ezixabisekileyo kunye nesikhokelo. Ngoko masiqalise!

Iibhodi zesekethe eziprintiweyo (PCBs) ziyinxalenye yezixhobo zombane zanamhlanje. Babonelela ngokuqhagamshelwa kombane kunye nenkxaso yamacandelo ahlukeneyo. Njengoko iteknoloji ihambela phambili, kuye kwavela uyilo oluntsonkothileyo nolusebenzayo lwePCB, kubandakanya neePCB eziguquguqukayo. Ezi bhodi zidibanisa izinto eziqinileyo neziguquguqukayo ukubonelela ukusebenza okuphuculweyo kunye nokusetyenziswa.

Funda malunga neebhodi eziguquguqukayo

Ngaphambi kokuba sixoxe ngenkqubo yokucoca iibhodi ze-rigid-flex, kuyimfuneko ukuqonda isakhiwo kunye nokubunjwa kwazo. I-PCB e-Rigid-flex yenziwe ngamaleko amaninzi ezinto eziqinileyo kunye neziguquguqukayo, ezifana ne-FR-4 kunye ne-polyimide. Ezi maleko ziqhagamshelwe kusetyenziswa iplate ngokusebenzisa imingxunya kunye nezihlanganisi flex. Banikezela ngezibonelelo ezinjengokugcina indawo, ukuqina okwandisiweyo kunye nokuphucula ukuthembeka.

Kutheni ucoce iibhodi eziqinileyo-flex?

Njengayo nayiphi na enye i-PCB, iibhodi eziguquguqukayo eziqinileyo zinokuqokelela uthuli, ukungcola, kunye nolunye ungcoliseko ngexesha lenkqubo yokuvelisa okanye ngexesha lokusetyenziswa. Ezi zingcolisi zinokuchaphazela ukusebenza kwe-PCB kunye nokuphila ixesha elide. Ngoko ke, ukucocwa rhoqo kuyadingeka ukuze kugcinwe ukusebenza kakuhle kunye nokuthintela iingxaki ezinokwenzeka.

Indlela yokucoca iibhodi eziqinileyo-flex

Xa ucoca iibhodi eziguquguqukayo, kubalulekile ukusebenzisa iindlela ezifanelekileyo kunye nezilumkiso zokuthintela ukonakalisa ibhodi. Nazi iindlela ezivunyiweyo zokucoca ezi bhodi:

1. Indlela ye-Isopropyl alcohol (IPA):Le ndlela ibandakanya ukosula ngobunono umphezulu we-PCB ngelaphu elingena-lint okanye i-cotton swab efakwe kwisisombululo se-IPA. IPA sisinyibilikisi esisetyenziswa ngokuqhelekileyo esisusa ngokufanelekileyo ukungcola ngaphandle kokushiya nayiphi na intsalela. Nangona kunjalo, kubalulekile ukusebenzisa ubuncinci be-IPA kwaye ugweme umswakama ogqithiseleyo njengoko unokungena kwiindawo eziguquguqukayo kwaye ubangele umonakalo.

2. Ukucoca nge-ultrasonic:Ukucocwa kwe-ultrasonic yindlela esetyenziswa ngokuqhelekileyo ekucoceni i-PCB. Kubandakanya ukuntywiliselwa i-PCB kwisisombululo sokucoca ngelixa iphathwa nge-ultrasonically. Iingqungquthela eziveliswa ngamaza zisusa ukungcola kwaye zihlambulule ngokufanelekileyo ibhodi yesiphaluka. Nangona kunjalo, ukulumka okugqithisileyo kufuneka kusetyenziswe xa usebenzisa le ndlela njengoko ukushisa okanye ukuxinzelela ngokugqithiseleyo kunokonakalisa iindawo eziguquguqukayo zePCB.

3. Ukucocwa kwesigaba somphunga:Ukucocwa kwesigaba somphunga yenye indlela esebenzayo yokucoca iibhodi ze-rigid-flex. Inkqubo ibandakanya ukuveza i-PCB kwisicoci esinomphunga, esijiya kumphezulu webhodi kwaye sinyibilikise ungcoliseko. Le teknoloji iqinisekisa ukucoceka okunzulu ngaphandle kokukhuthaza nayiphi na intrusion yomswakama. Nangona kunjalo, ifuna izixhobo ezikhethekileyo kunye nobuchule, okwenza ukuba kufikeleleke kancinci kumsebenzisi oqhelekileyo.

Amanyathelo okhuseleko aya kulandelwa

Ngelixa ukucoca iibhodi eziguquguqukayo kubalulekile, kubalulekile ngokulinganayo ukulandela izilumkiso ezithile zokuthintela nawuphi na umonakalo. Nanga amanye amacebiso omele uwakhumbule:

1. Kuphephe ukusebenzisa izinto ezirhabaxa:Musa ukusebenzisa izinto ezirhabaxa ezifana neebhrashi okanye iipads zokukhuhla njengoko zinokukrwela okanye zonakalise umphezulu obuthathaka wePCB.

2. Musa ukuntywilisela i-PCB emanzini:Musa ukuntywilisela i-PCB kuso nasiphi na isisombululo solwelo ngaphandle kokuba usebenzisa indlela evunyiweyo njengokucoca nge-ultrasonic. Ukufuma okugqithisileyo kunokungena kwiindawo eziguquguqukayo kwaye kubangele umonakalo.

3. Phatha ngenkathalo:Soloko uphatha ii-PCBs ngezandla ezicocekileyo kwaye uphephe ukugoba okanye ukugoba ibhodi ngaphaya kwemida yayo njengoko oku kunokubangela iintanda zoxinzelelo okanye ukwaphuka.

Ukuququmbela:

Isishwankathelo, ewe, unokuhlamba okanye ukucoca iibhodi ze-rigid-flex, kodwa kufuneka ulandele iindlela ezichanekileyo kunye nezilumkiso zokukhusela nawuphi na umonakalo. Ukucoca rhoqo kunceda ukugcina ukusebenza kunye nokuphila ixesha elide kwezi PCB eziphambili. Ingaba ukhetha indlela ye-IPA, ukucocwa kwe-ultrasonic okanye ukucoca umphunga, qaphela kwaye ugweme umswakama obuninzi okanye uxinzelelo.

Ukuba awuqinisekanga ukuba ungayicoca njani ibhodi eqinileyo okanye uphathe nayiphi na eminye imiba enxulumene nokugcinwa, kuyacetyiswa ukuba ufune uncedo lobuchwephesha okanye udibane nomenzi wePCB. Ukugcina i-PCB yakho icocekile kwaye igcinwe kakuhle kuya kuqinisekisa ukusebenza okugqwesileyo kunye nokuthembeka kwezixhobo zakho zombane.
