Imingeni kunye nezisombululo zokubhola nge-PCB ekhawulezayo: Ukuthintela i-ICD kunye nokuphucula izixhobo

Isiqulatho

• Intshayelelo
• Imingeni ephambili kwi-High-Speed ​​​​PCB Drilling
• Uyilo lweDrill Bit kunye noLungiso lweCoating
• Ukulungiswa kweParameter yeNkqubo
• Isiphelo

Ngenxa yokwamkelwa ngokubanzi kwezixhobo ezikhawulezayo kunxibelelwano lwe-5G, izixhobo ze-elektroniki zeemoto, kunye nekhompyutha esebenza kakhulu, abavelisi be-PCB bajongene neemfuno ezikhulayo zokuchaneka kokubhola, ukusebenza kakuhle, kunye nokuthembeka. Iimpawu ezikhethekileyo zezixhobo ezikhawulezayo—ukulahleka okuphantsi kokudluliselwa, ukumelana nobushushu obuphezulu, kunye namandla oomatshini—ziphucula kakhulu ukusebenza kwe-PCB kodwa zikwazisa nemingeni emikhulu kwiinkqubo zokubhola. Phakathi kwezi, i-ICD (Inner Connection Defects) ibe yinto ebalulekileyo echaphazela isivuno kunye nokuthembeka kwe-PCB.

Imingeni ephambili kwi-High-Speed ​​​​PCB Drilling

• Iziphene ze-ICD: Ngexesha lokuhlanganiswa kwe-SMT kunye nokuphinda kusebenze ubushushu obuphezulu, ukwahlukana kwe-resin okanye ukuqhekeka kunokubakho, okukhokelela ekuqhagamshelweni okubi kwe-inside-layer.
• Ubomi be-Drill Bit obuncitshisiweyo: Ukungqubana okuphezulu kunye noxinzelelo lobushushu ngexesha lokugrumba kukhawulezisa ukuguguleka kwezixhobo, kunciphisa ubomi be-drill ngaphezulu kwe-50%.
• Ukusebenza Kancinci Kokucubungula: Iibhithi zokubhola zesiqhelo zifuna ukuncitshiswa kwesantya esingaphezulu kwama-20% xa kusetyenzwa izixhobo ezikhawulezayo, nto leyo ethintela imveliso iyonke.

Uyilo lweDrill Bit kunye noLungiso lweCoating

• Uyilo lweDrill Bit: Izifundo zibonisa ukuba iidrill ze-USF ezine-single-edge double-edge single-flute kunye needrill ezine-SHC zibonelela ngokusebenza okuhle kakhulu ekubholeni izinto ngesantya esiphezulu. Uyilo lwe-USF lunceda ekunciphiseni ukwakheka kwe-ICD, ngelixa ii-SHC coatings zonyusa ukumelana nokuguguleka kunye nobomi bezixhobo.
• Iingenelo zokugquma: Xa kuthelekiswa nokugrumba okuqhelekileyo, izixhobo ezigqunywe yi-SHC zandisa ubomi bezixhobo ngaphezulu kwe-30% ngelixa zigcina umgangatho wemingxuma uhambelana, nto leyo ezenza zibe zilungele ukwenziwa kwe-PCB enomthamo ophezulu, nesantya esiphezulu.

Ukulungiswa kweParameter yeNkqubo

Uvavanyo lokuthelekisa lubonisa ukuba:

• Ukulungiswa okufanelekileyo kwesantya sokutya kunye nesantya sokusika kunciphisa kakhulu ukwakheka kwe-burr kunye nomonakalo wodonga lwemingxuma.
• Kwi-substrates ezinesantya esiphezulu ze-0.25 mm, iidrill ezine-SHC-coated zigcine umgangatho ozinzileyo kangangee-hits ezingaphezu kwama-600, ngelixa iidrill eziqhelekileyo zibonakalise ukonakala okukhulu emva kwee-hits ezingama-400.

Ukujongana nemingeni yokubhola nge-PCB ekhawulezayo, uyilo lwe-drill oluphuculweyo, ubuchwepheshe bokugquma obuphambili, kunye neeparamitha zenkqubo ezilungisiweyo zibalulekile. Njengomvelisi we-PCB kunye ne-PCBA ochwephesha, asinikeli nje kuphela amandla okubhola ngokuchanekileyo kodwa sikwabonelela ngezisombululo zokuphucula inkqubo ezinokuthenjwa nezisebenzayo ezilungiselelwe iimfuno zabathengi bethu.
