6 Layer ENIG Impedance Kudzora PCB

PCB yakagadzira kubva kune rimwe divi kuenda kune kaviri kudivi uye multilayer, uye chikamu che multilayer PCB chiri kuwedzera gore negore.Kuita kwe multilayer PCB kuri kusimukira kusvika padanho repamusoro, dense uye rakanaka.Lamination inzira yakakosha mukugadzira multilayer PCB.Kudzora kwemhando yelamination kuri kuwedzera kukosha.Nokudaro, kuitira kuti tive nechokwadi chemhando ye-multilayer laminate, tinofanira kuva nekunzwisisa zviri nani kwemaitiro e-multilayer laminate.Nzira yekuvandudza sei kunaka kwe multilayer laminate?

1. Ukobvu hwepakati peplate hunofanira kusarudzwa maererano nehuwandu hwehuwandu hwePCB yakawanda.Ukobvu hwepakati peplate hunofanirwa kuenderana, kutsauka kuri kudiki, uye nzira yekucheka inopindirana, kuitira kudzivirira zvisina kufanira kubhenda kweplate.

2. Panofanira kunge kune imwe nzvimbo pakati pehupamhi hwepakati peplate uye chikwata chinoshanda, ndiko kuti, chinhambwe pakati pechikamu chinoshanda uye chidimbu cheplate chinofanira kunge chakakura sezvinobvira pasina kuparadza zvinhu.

3. Kuti kuderedze kutsauka pakati pezvikamu, kunyanya kukoshesa kunofanira kubhadharwa kune kugadzirwa kwekutsvaga makomba.Nekudaro, iyo yakakwira huwandu hweakagadziridzwa makomba ekumisikidza, maburi erivet uye maburi emidziyo, ndiko kuwedzera kwehuwandu hwemaburi akagadzirwa, uye chinzvimbo chinofanira kunge chiri padyo nedivi sezvinobvira.Chinangwa chikuru ndechekudzikisa kutsauka kwekuenzanisa pakati pematanho uye kusiya imwe nzvimbo yekugadzira.

4. Iyo yemukati bhodhi bhodhi inodiwa kuti ive isina yakavhurika, pfupi, yakavhurika yedunhu, oxidation, yakachena bhodhi kumusoro uye yakasara firimu.
