PCB Immersion Gold VS Gold Plated Board

Ezweni eliyinkimbinkimbi lokukhiqizwa kwezinto zikagesi, amaBhodi Esifunda Aphrintiwe (ama-PCB) ayizingxenye eziyisisekelo. Ukuphela kobuso okusetshenziswa kula mabhodi kuyisici esibalulekile esithinta kakhulu ukusebenza kwawo kanye nobude bawo. Lesi sihloko sihlose ukukhanyisa izinhlobo ezimbili ezivelele zokuphela kobuso be-PCB - i-PCB Immersion Gold kanye ne-Gold Plated Boards - ukuhlola izici zawo, izinzuzo, kanye nendlela aqhathaniswa ngayo.

Iyini i-PCB Surface Finishes

Ukuqeda okungaphezulu kufakwa emigqeni yethusi ye-PCB ukuze ivikeleke ekushisweni yi-oxidation futhi inikeze indawo eshiswayo lapho kuhlanganiswa izingxenye ze-elekthronikhi. Ukukhetha ukuqeda okungaphezulu kungathinta izici ezahlukahlukene zokusebenza kwe-PCB, okuhlanganisa ukushiswa, ukuhanjiswa kwamandla, kanye nesikhathi sokuphelelwa yisikhathi. Kunezinhlobo eziningana zokuqeda okungaphezulu kwe-PCB ezitholakala emakethe, ngayinye inezakhiwo zayo ezihlukile kanye nezinhlelo zokusebenza. Lokhu kufaka phakathi i-HASL (Hot Air Solder Leveling), i-OSP (Organic Solderability Preservatives), i-Immersion Silver, i-Immersion Tin, i-Immersion Gold, kanye ne-Gold Plated finishes.

Phakathi kwalokhu, i-PCB Immersion Gold kanye neGold Plated Boards azuze ukuvelela ngenxa yezimfanelo zawo eziphakeme. I-PCB Immersion Gold, eyaziwa ngokuba isicaba nokuthembeka okuhle kakhulu, ihlanganisa ukusebenzisa ungqimba oluncane lwegolide phezu kwe-nickel substrate. Ngakolunye uhlangothi, I-Gold Plated Boards ivamise ukufaka isendlalelo segolide esijiyile, esinikeza ukuqina okuthuthukisiwe kanye nokusebenza kahle.

Iyini i-PCB Immersion Gold

I-PCB Immersion Gold, eyaziwa nangokuthi i-Electroless Nickel Immersion Gold (ENIG), iwuhlobo lokuqedwa kwendawo esetshenziselwa amabhodi esekethe aphrintiwe anikeza kokubili izinzuzo zokusebenza nezobuhle. Lesi sigaba sihlola izici ezibalulekile kanye nezinzuzo ze-Immersion Gold PCBs.
