Kuchera
Chinangwa
Dhobora nepakati/mapofu maburi paCCLs kuti utange kuwirirana pakati pematanho edunhu uye pakati pemidziyo nemaseketi.
Al: kupisa kupisa
Copper foil: conductive layer
Baseboard: kudzivirira drill bit kukuvara
Kuchera mamiriro uye kugona
1. Mamiriro ekuchera:
* Feeds: Kudzika kwekuchera paminiti
* Kumhanya: Nhamba yekutenderera paminiti
* Huwandu hwekubvisa tsvina: Hudzamu hunogona kupinzwa nekutenderera kwega kwega huwandu hwayo hwekubvisa tsvina
2. Kugona kuchera:
* Saizi shoma yegomba: kana gomba rakacherwa nemuchina, saizi shoma yegomba ndeye 0.2mm
* Gomba chinzvimbo kushivirira (kazhinji ± 3mil)
* Gomba saizi kushivirira (kazhinji +0/-1mil)
