Ezona ntlobo ziNxibelelayo ze-Ecapsulating kunye ne-Potting Compounds zePCB

Iibhodi zeesekethe eziprintiweyo ziyinxalenye ebaluleke kakhulu ye-elektroniki. Zisebenza njengengqondo kuninzi kwaye ke kufuneka zikhuselwe kangangoko kunokwenzeka kuzo zonke izinto eziyingozi. Ukubumba kuphakathi kweendlela ezisetyenziselwa ukunika ukhuseleko olufuneka kakhulu kwiibhodi okanye ii-substrates. Inkqubo yenziwa ngokuzalisa izindlu zePCB ngeyona khompawundi ifanelekileyo yolwelo. Ikhompawundi ishiywe ukuba inyangwe phambi kokukhusela ngokupheleleyo iindawo ezibalulekileyo ze-elektroniki.

Ngaphandle kwezindlu, ukuzaliswa kunokugubungela ibhodi yonke kunye namacandelo. Kwakhona kunokwenziwa kumacandelo athile ngokuxhomekeke kwiimfuno. Le yeyona ndlela ibalaseleyo yokugcina i-abrasion, ubushushu, imichiza kunye nomonakalo wokusingqongileyo kwindawo. Izinto ezahlukeneyo zisetyenziswa njenge iikhompawundi potting for PCB, kwaye ezona ziphambili ziyi-silicone, i-epoxy, kunye ne-polyurethane.

1. I-Epoxy 

Esi sixhobo sokubumba se-PCB siqhele ukuthandwa ngenxa yokuqina kwayo kunye nokumelana neekhemikhali. Ikwabonelela nge-adhesion ephezulu ebotshelelwe ukuhlala ixesha elide kakhulu. Nangona kunjalo, izinto zithatha ixesha elide ukunyanga kwaye zifuna ixesha lokuseta.

2. lyu

Njengesixhobo sokubumba, i-polyurethane ithambile xa ithelekiswa ne-epoxy. Yenza ukhetho olufanelekileyo kwizihlanganisi ezinovakalelo kunye namalungu e-elektroniki angakwaziyo ukunyamezela izinto eziqinileyo ezifana ne-epoxy. Nangona kunjalo, ukuxhathisa ubushushu kunye nokufuma koku i-potting compound ayomelele kangako.

3. abicah 

I-Silicone ithandwa ngenxa yokuguquguquka kwayo kunye nokuqina. Mhlawumbi yeyona nto idumileyo yokubumba imathiriyeli namhlanje kuba ifanele izicelo ezininzi kwaye inokumelana namaqondo obushushu agqithisileyo. Owona mceli mngeni kuphela kukuba inokubiza kakhulu, iyenze ingasebenzi kwezinye izicelo.

Ingaba imbiza iyimfuneko?

I-Potting ibonelela ngendlela elula nekhawulezayo yokubonelela ngokhuseleko kuzo zonke izicelo. Kulula ukufaka isicelo kwiimveliso eziphezulu kunye nemigca yendibano. Xa kuthelekiswa neentyantyambo ezibhityileyo ezihambelanayo, ukubunjwa kwembiza kunika iidyasi ezishinyeneyo ezikwaziyo ukuqina kwaye zomelele. Ngokubeka i-PCB yakho, ubanika:

• Ukuxhathisa okuphezulu kwiikhemikhali, iingozi zokusingqongileyo, ukungcangcazela, kunye nobushushu
• Ukonyuka kokuqina, ngakumbi ngokuchasene ne-abrasions kunye neempembelelo
• Ukhuseleko loyilo olongezelelweyo, ngakumbi xa usiya kwiikhompawundi ezinombala omnyama
• Ukukhuselwa okukhulu kwii-arcs zombane kunye nomonakalo wamanzi

Izixhobo ezifakwe emanzini, nangona kunjalo, zinokuba ngumngeni wokuphinda zisebenze ngenxa yokuba ukususa i-potting kunokuphelisa ukutshabalalisa ibhodi yesiphaluka. Xa kuthelekiswa nezixhobo ezigqunywe ngezinto ezilungelelanisiweyo, zingumngeni kakhulu ukusebenza nazo. Ukubumba kwakhona kuza kunye nezinye izinto ezingeloncedo, kubandakanya:

• Ukungabi bhetyebhetye
• Iindleko eziphezulu
• Ukunyuka kobunzima obubalulekileyo kwi-PCBs
• Amanyathelo okuqhubela phambili ongezelelweyo

Kodwa nangona imiceli mngeni, izinto zokubumba ozikhethela amacandelo akho zihlala zichaza uhlobo lwamava owafumanayo. Kwaye ngeendlela ezininzi, uya kuhlala ufumana imathiriyeli efanelekileyo kwiimfuno zakho zesicelo. Iikhompawundi zokubumba zibonelela ngeenzuzo ezifanayo kwibhodi yonke, kodwa uphawu olukhethayo lunokugqiba umgangatho owufumanayo.

Eyona nto ingcono ongayenza kwiibhodi zakho zesekethe kukukhetha iimveliso onokuthi uzithembe ngokupheleleyo okanye umgangatho. Iimveliso ezivela kwi-Deep Material zezinye zezona zibalaseleyo kwimarike ukuya kuthi ga ngokomgangatho. Eyona nto ilungileyo malunga nenkampani inoluhlu olubanzi lweemveliso kwaye kulula ukufumana oko kuhambelana neemfuno zakho. Okona kungcono, unokuba nemveliso ekhethekileyo eyenzelwe ukuhambelana neemfuno zakho.

Ukufumana okungakumbi malunga neentlobo eziphambili ze-encapsulating kunye iikhompawundi potting for pcb,unokuhlawula utyelelo kwi-DeepMaterial kwi https://www.epoxyadhesiveglue.com/epoxy-potting-compound-for-pcb-the-options-and-benefits/ ngolwazi olungakumbi.
