Kopanong ea PCBA, khetho ea thepa e bohlokoa ho ts'ebetso ea boto le ho ts'epahala.Mona ke lintlha tse ling tsa ho khetha solder, PCB le khetho ea thepa ea ho paka:
Litaelo tsa khetho ea solder
1. Lead Free Solder vs Leaded Solder
Solder e se nang loto e bohlokoa ka lebaka la botsoalle ba eona ba tikoloho, empa ke habohlokoa ho hlokomela hore e na le mocheso o phahameng oa soldering.Solder e etellang pele e sebetsa ka mocheso o tlase, empa ho na le likotsi tsa tikoloho le bophelo bo botle.2.
2. Ntho e qhibilihang
Etsa bonnete ba hore ntlha e qhibilihang ea solder e khethiloeng e loketse litlhoko tsa mocheso oa ts'ebetso ea kopano 'me e ke ke ea baka tšenyo ea likarolo tsa mocheso.
3. Mokelikeli
Netefatsa hore solder e na le mokelikeli o motle ho etsa bonnete ba hore ho na le metsi a lekaneng le ho hokahanya ha manonyeletso a solder.
4. Ho hanyetsa mocheso
Bakeng sa lisebelisoa tse phahameng tsa mocheso, khetha solder e nang le mocheso o motle oa ho hanyetsa mocheso ho netefatsa botsitso ba motsoako oa solder.
Lintlha tsa khetho ea lisebelisoa tsa PCB
1. Lisebelisoa tsa substrate
Khetha thepa e loketseng ea substrate, joalo ka FR-4 (fiber fiber reinforced epoxy resin) kapa lisebelisoa tse ling tsa maqhubu a phahameng, ho ipapisitsoe le litlhoko tsa ts'ebeliso le litlhoko tsa khafetsa.
2. Palo ea Lihlopha
Etsa qeto ea palo ea likarolo tse hlokahalang bakeng sa PCB ho finyella litlhoko tsa ho tsamaisa melaetsa, lifofane tsa fatše le tsa matla.
3. Impedans ea sebopeho
Utloisisa sebopeho sa ts'ebetso ea thepa e khethiloeng ea substrate ho netefatsa botšepehi ba matšoao le ho tsamaisana le litlhoko tse fapaneng tsa para.
4. Thermal Conductivity
Bakeng sa lisebelisoa tse hlokang ho senya mocheso, khetha thepa ea substrate e nang le conductivity e ntle ea mocheso ho thusa ho senya mocheso.
Lintlha tsa khetho ea thepa ea sephutheloana
1. Mofuta oa sephutheloana
Khetha mofuta o nepahetseng oa sephutheloana, joalo ka SMD, BGA, QFN, joalo-joalo, ho latela mofuta oa karolo le litlhoko tsa ts'ebeliso.
2. Boitsebiso ba encapsulation
Netefatsa hore thepa e khethiloeng ea encapsulation e kopana le litlhoko tsa ts'ebetso ea motlakase le mochini.Nahana ka lintlha tse kang mocheso oa mocheso, ho hanyetsa mocheso, matla a mochine, joalo-joalo.
3. Pakete tshebetso mocheso
Bakeng sa lisebelisoa tse hlokang ho felloa ke mocheso, khetha thepa ea sephutheloana e nang le ts'ebetso e ntle ea mocheso, kapa u nahane ka ho eketsa mocheso oa mocheso.
4. Boholo ba sephutheloana le sekheo sa phini
Netefatsa hore boholo le sebaka sa sekhechana sa sephutheloana se khethiloeng se loketse sebopeho sa PCB le sebopeho sa karolo.
5. Tšireletso le ts'ireletso ea tikoloho
Nahana ka ho khetha thepa e baballang tikoloho e lumellanang le melao le litekanyetso tse amehang.
Ha u khetha thepa ena, ke habohlokoa ho sebetsa haufi-ufi le baetsi ba PCBA le bafani ba thepa ho etsa bonnete ba hore khetho ea thepa e kopana le litlhoko tsa kopo e itseng.Hape, ho utloisisa melemo, likotsi le litšobotsi tsa lisebelisoa tse fapaneng, hammoho le ho tšoaneleha ha tsona bakeng sa lits'ebetso tse fapaneng, ke senotlolo sa ho etsa khetho e nepahetseng.Ho nahanoa ka mokhoa o tlatsetsang oa solder, PCB le thepa ea ho paka e tiisa ts'ebetso le botšepehi ba PCBA.
Zhejiang NeoDen Technology Co., LTD., E thehiloe ka 2010, ke moetsi ea hloahloa ea khethehileng ka mochini oa ho khetha le ho beha sebaka sa SMT, onto ea reflow, mochini oa khatiso oa stencil, mohala oa tlhahiso ea SMT le Lihlahisoa tse ling tsa SMT.Re na le sehlopha sa rona sa R&D le feme ea rona, re nka monyetla ka R&D ea rona e ruileng e nang le boiphihlelo, tlhahiso e koetlisitsoeng hantle, e hapileng botumo bo botle ho tsoa ho bareki ba lefats'e ka bophara.
