Ngenxa yoko, abavelisi banokuvelisa iigajethi ezincinci, ezithandekayo ngaphandle kokuphazamisa ukusebenza.

4. Phucula ukuhanjiswa komqondiso:
IiPCB eziguquguqukayo zigcina nkqu ukuhamba kombane kwisekethe, ukunciphisa ilahleko yesiginali kunye nokuphazamiseka. Ngenxa yoyilo lwazo oludibeneyo, ezi bhodi zikwabonisa ukuchasana okuphantsi kunye ne-capacitance, ukuphucula ingqibelelo yesignali. Le nzuzo ibaluleke kakhulu kwizicelo apho izibonakaliso ze-high-frequency okanye ulungelelwaniso oluchanekileyo ludlala indima ebalulekileyo, njenge-aerospace, unxibelelwano kunye nezixhobo zonyango.

5. Ukusebenza kakuhle kweendleko:
Nangona ii-PCB eziguquguqukayo zineengenelo ezininzi, zisenokuba nexabiso eliphantsi kwezinye iimeko. Uphuhliso olukhawulezayo lwetekhnoloji yokuvelisa ezifana ne-roll-to-roll processing kunye noshicilelo lwe-3D yenze ukuveliswa kwee-PCB eziguquguqukayo ngokukhawuleza kwaye kungabizi kakhulu. Ukongeza, indalo yabo ekhaphukhaphu inokuphucula ngakumbi ukukhuphisana kwabo kwintengiso ngokunciphisa iindleko zothutho kunye nokuvumela ukusetyenziswa kwezinto ezinexabiso eliphantsi ukunciphisa iindleko zizonke.

Ububi bePCB ebhetyebhetye:

1. Uyilo kunye nobunzima bokuvelisa:
Ukuyila ii-PCB eziguquguqukayo kufuna izakhono ezikhethekileyo kunye nolwazi oluphucukileyo lwezixhobo eziguquguqukayo, i-radii yokugoba kunye nobuchule bokuhlanganisa. Ukuntsonkotha kwenkqubo yoyilo kudala imingeni kwiinjineli eziqhele ukuyila ibhodi yesekethe engqongqo. Ngokufanayo, ukuvelisa iibhodi zesekethe eziguquguqukayo eziprintiweyo kubandakanya izixhobo ezithile kunye neenkqubo, okukhokelela ekunyuseni iindleko zemveliso, ngakumbi kwiiprojekthi ezincinci.

2. Ukunciphisa ubushushu obuncinci:
Ngokungafaniyo nee-PCB eziqinileyo, ii-PCB eziguquguqukayo zinamandla okuphelisa ubushushu.
