Sanibonani nonke, yimina mhleli.Ngokusho kwezitayela zemakethe, izixhumi zebhodi ukuya ebhodini ziye zaba nezinguquko ezinkulu eminyakeni yamuva, futhi izixhumi zebhodi ukuya ebhodini ziye zaba zincane futhi zaba zincane.I-pitch evamile yamanje yesixhumi sebhodi ukuya ebhodini ngu-0.40 mm;nakuba ukuphakama kwesitaki okungu-1 mm kuyisixhumi esincane, abakhiqizi abakhulu bezinhlelo zokusebenza zokuxhuma ibhodi ukuya ebhodini basebenzisa izixhumi zebhodi ukuya ebhodini eziphansi njengo-0.70 mm noma ngisho nangaphansi.Ngakho-ke ungakhetha kanjani usayizi wesixhumi sebhodi ukuya ebhodini?Umhleli olandelayo uchaza indlela yokukhetha usayizi wesixhumi sebhodi ukuya ebhodini!

Eminyakeni embalwa edlule, izixhumi ezindala ezincane ezinobubanzi obungaphezu kuka-4 mm zathathelwa indawo yizixhumi ezibanzi ezingu-3.40 mm.Umqondo wamanje wesixhumi sebhodi ukuya ebhodini uvamise ukuba kububanzi obungu-2.40 ukuya ku-2.60 mm.Enkambweni yokukhetha isixhumi sebhodi ukuya ebhodini, okuncane kungcono, ngoba kuncane, indawo etholakalayo izokwanda.

I-PIN HEADER PITCH:1.0MM(.039″) UHLOBO OKUQONDILE OKUMBHALI OKUMAMBILI

Ngaphambi kokuthi sikhethe ukusebenzisa isixhumi sebhodi ukuya ebhodini esincanyana kakhulu, sidinga ukwazi ukuthi isixhumi sinazo zonke ezinye izici ozidingayo, futhi sisihlole ngokucophelela ukuze siqiniseke ukuthi siqine ngokwanele.Khona-ke, isokhethi elinesixhumi esifakwe phezulu siyadingeka ngoba lesi silungiselelo singalandelelwa ngaphansi kwesokhethi futhi i-conformal coating ingasetshenziswa kalula.Okunye okungalungile kwamasokhethi afakwe phezulu ukuthi ububanzi bendawo yokucosha ivacuum kuvame ukuba mncane endaweni yesokhethi futhi ayikho impahla yegobolondo lepulasitiki, kodwa ingavimbela inkinga ebangelwa uwoyela ongahluziwe ongalingani phezulu. isokhethi.

Ukuze kuqinisekiswe ukuthi isixhumi esikhethiwe sebhodi ukuya ebhodini singanqanyulwa ngokushesha, umsebenzi wokukhiya isixhumi wobude obengeziwe ungase udingeke ukuze kubonakale isixhumi sebhodi ukuya ebhodini sosayizi odingekayo.Naka izixhumi ezengeziwe ukuze unqamule Ukusebenza ngokuvamile kusho ukubamba iqhaza okukhulu, ngoba kungase kubangele izinkinga ngamasekhethi amakhulu.
