Yazisa:

Kwimveliso ye-elektroniki, i-soldering idlala indima ebalulekileyo ekuqinisekiseni ukuthembeka kunye nokusebenza kweebhodi zeesekethe eziprintiweyo (PCBs). I-Capel ineminyaka eyi-15 yamava eshishini kwaye ingumnikezeli okhokelayo wezisombululo ze-PCB eziphuculweyo.Kwesi sikhokelo sibanzi, siza kuphonononga iinkqubo ezahlukeneyo zokuthengisela kunye nobuchule obusetyenziswa kwi-PCB yokwenziwa, siqaqambisa ubuchule beCapel kunye neteknoloji yenkqubo ephezulu.

1. Ukuqonda PCB soldering: Overview

PCB solder yinkqubo yokudibanisa amacandelo elektroniki PCB usebenzisa solder, ingxubevange yesinyithi inyibilika kumaqondo obushushu aphantsi ukwenza ibhondi. Le nkqubo ibalulekile kwimveliso yePCB njengoko iqinisekisa ukuhanjiswa kombane, uzinzo kumatshini kunye nolawulo lobushushu. Ngaphandle kwe-soldering eyiyo, iPCB ayinakusebenza okanye iqhube kakubi.

Kukho iintlobo ezininzi zeendlela zokuthengisela ezisetyenziswa kwimveliso yePCB, nganye inezicelo zayo ezisekelwe kwiimfuno ezithile zePCB. Ezi teknoloji ziquka iteknoloji ye-surface Mount (SMT), ngokusebenzisa iteknoloji ye-hole (THT) kunye neteknoloji ye-hybrid. I-SMT iqhele ukusetyenziselwa amacandelo amancinci, ngelixa i-THT ikhethwa kwizinto ezinkulu kunye nezomelele ngakumbi.

2. PCB welding technology

A. Iteknoloji yokuwelda yemveli

I-welding enye kunye namacala amabini
I-solder enecala elinye kunye necala-mbini zisetyenziswa ngokubanzi iindlela zokwenziwa kwePCB. I-soldering enecala elinye ivumela izinto ukuba zithengiswe kwicala elinye kuphela le-PCB, ngelixa i-solder emacala amabini ivumela izinto ukuba zithengiswe macala omabini.

Inkqubo ye-solder ecalanye ibandakanya ukusebenzisa i-solder paste kwi-PCB, ibeka i-surface mount components, kwaye emva koko iphinda ikhuphe i-solder ukudala ibhondi eyomeleleyo. Le teknoloji iboleka kuyilo olulula lwePCB kwaye ibonelela ngeengenelo ezifana nokusebenza kweendleko kunye nokuhlangana ngokulula.

I-solder emacala amabini,kwelinye icala, ibandakanya ukusebenzisa amacandelo ngomngxuma ezithengiswa macala omabini PCB. Le teknoloji yandisa ukuzinza komatshini kwaye ivumela ukuhlanganiswa kwamacandelo amaninzi.

I-Capel igxile ekufezekiseni iindlela ezithembekileyo ze-welding enye kunye namacala amabini,ukuqinisekisa umgangatho ophezulu kunye nokuchaneka kwinkqubo ye-welding.

I-Multilayer PCB soldering
Ii-PCB ze-Multilayer zenziwe ngamaleko amaninzi obhedu kunye nezixhobo zokugquma, ezifuna ubuchule obukhethekileyo bokuthengisa. I-Capel inamava amaninzi okuphatha iiprojekthi ze-welding multi-layer welding, eqinisekisa ukudibanisa okuthembekileyo phakathi kweeleyile.

Inkqubo yokuthengisela yePCB eninzi ibandakanya imingxuma yokugrumba kumaleko ngamnye we-PCB kwaye emva koko ugqume imingxuma ngezinto zokuqhuba. Oku kuvumela amacandelo ukuba athengiswe kumaleko angaphandle ngelixa ugcina uxhulumaniso phakathi kwemigangatho yangaphakathi.

B. Iteknoloji ye-welding ephuculweyo

I-HDI PCB yokuthengisa
High-density interconnect (HDI) PCBs zisiya zithandwa kakhulu ngenxa yokukwazi kwazo ukwamkela amacandelo amaninzi kwizinto ezincinci. Itekhnoloji yokuthengisa ye-HDI PCB yenza i-solder echanekileyo yeekhomponenti ezincinci kuyilo olunoxinaniso oluphezulu.

Ii-PCB ze-HDI zijongene nemiceli mngeni ekhethekileyo efana nezithuba ezixineneyo zecandelo, iinxalenye ze-pitch-pitch, kunye nesidingo setekhnoloji ye-microvia. Itekhnoloji yenkqubo ephucukileyo ye-Capel yenza ukuba i-HDI ithengise i-PCB echanekileyo, iqinisekisa umgangatho ophezulu kunye nokuthembeka kolu yilo oluntsonkothileyo lwePCB.

Ibhodi eguquguqukayo kunye nebhodi eqinile-flex welding
I-Flexible kunye ne-rigid-flex iibhodi zesekethe eziprintiweyo zibonelela ngokuguquguquka kunye nokuguquguquka kokuyila, okwenza zibe zilungele izicelo ezifuna ukugoba okanye izinto ezidibeneyo. I-Soldering ezi ntlobo zeebhodi zeesekethe zifuna izakhono ezikhethekileyo zokuqinisekisa ukuqina kunye nokuthembeka.

Ubuchwephesha beCapel kwi-soldering flexible and rigid-flex PCBsiqinisekisa ukuba ezi bhodi zinokumelana nokugoba ngokuphindaphindiweyo kwaye zigcine ukusebenza kwazo. Ngeteknoloji yenkqubo ephezulu, iCapel ifezekisa ama-solder athembekileyo nakwiindawo eziguquguqukayo ezifuna ukuguquguquka.

3. Itekhnoloji yenkqubo ephezulu yaseCapel

I-Capel izimisele ukuhlala phambili kwishishini ngokutyala imali kwizixhobo zanamhlanje kunye neendlela ezintsha. Itekhnoloji yabo yenkqubo ephucukileyo ibenza bakwazi ukubonelela ngezisombululo zokusika kwiimfuno ezintsonkothileyo ze-welding.

Ngokudibanisa izixhobo ze-solder eziphezulu ezifana noomatshini bokubeka ngokuzenzekelayo kunye nee-ovens zokuphinda zigqithise kunye nabachwephesha abanezakhono kunye neenjineli, iCapel ihlala ihambisa iziphumo eziphezulu ze-soldering. Ukuzinikela kwabo ekuchanekeni nasekuveliseni izinto ezintsha kubabeka bucala kwishishini.

Isishwankathelo

Esi sikhokelo esibanzi sinika ukuqonda okunzulu kweenkqubo zokuthengisela i-PCB kunye nobuchule. Ukusuka kwi-solder yendabuko enecala elinye kunye necala eliphindwe kabini ukuya kwiiteknoloji eziphambili ezifana ne-HDI PCB yokuthengisa kunye ne-flexible PCB soldering, ubuchule beCapel bukhanya.

Ngeminyaka eyi-15 yamava kunye nokuzibophelela kwiteknoloji yenkqubo ephezulu, uCapel ungumlingane othembekileyo kuzo zonke iimfuno ze-PCB ze-solder. Qhagamshelana neCapel namhlanje ukuze ufumane izisombululo ezithembekileyo, eziphezulu ze-PCB ezithengiswayo, ezixhaswa ngubugcisa babo kunye nobuchwepheshe obuqinisekisiweyo.
