Sechikamu chakakosha chezvese zvigadzirwa zvemagetsi, tekinoroji yakakurumbira munyika inoda yakakwana PCB design. Zvisinei, iyo nzira pachayo dzimwe nguva haina chinhu. Yakapfava uye yakaoma, zvikanganiso zvinowanzoitika muPCB dhizaini maitiro. Nekuda kwekunonoka kwekugadzira kunokonzerwa nedunhu bhodhi reflow, zvinotevera zvitatu zvakajairika PCB zvikanganiso izvo zvinofanirwa kucherechedzwa kudzivirira zvikanganiso zvekushanda.

1.) Kumhara mode

Kunyangwe mazhinji PCB dhizaini software ichisanganisira General Electric chikamu maraibhurari, yavo inoenderana schematic zviratidzo uye kumhara mapatani, mamwe edunhu mabhodhi anozoda vagadziri kuti vaadhirowe nemaoko. Kana iko kukanganisa kuri pasi pehafu yemirimita, injinjini inofanirwa kuve yakasimba kwazvo kuti ive nechokwadi chekuyera kwakaringana pakati pemapads. Kukanganisa kunoitwa panguva ino yekugadzira kuchaita kuti welding yakaoma kana kusaita. Iyo inodiwa rework ichakonzera kunonoka kunodhura.

2.) Shandisa vias mapofu/akavigwa

Mumusika wemidziyo yakajairira kushandisa IoT nhasi, zvidiki uye zvidiki zvigadzirwa zvinoramba zvichipa simba guru. Kana midziyo midiki inoda maPCB madiki, mainjiniya mazhinji anosarudza kushandisa mapofu uye akavigwa vias kuderedza tsoka yebhodhi redunhu kubatanidza zvidimbu zvemukati nekunze. Kunyangwe iyo kuburikidza negomba inogona kunyatso kudzikisa nzvimbo yePCB, inoderedza nzvimbo yewaya, uye sezvo huwandu hwekuwedzera hunowedzera, hunogona kuve hwakaoma, izvo zvinoita kuti mamwe mabhodhi adhure uye asingakwanise kugadzira.

3.) Rondedzera upamhi

Kuti uite kuti saizi yebhodhi ive diki uye compact, chinangwa cheinjiniya ndechekuita kuti mitsetse iite nhete sezvinobvira. Kusarudza PCB yekutsvaga hupamhi kunosanganisira zvakawanda zvakasiyana, izvo zvinoita kuti zviome, saka zvinodikanwa kuti unzwisise zvizere kuti mangani milliamps achadikanwa. Muzviitiko zvakawanda, hupamhi hudiki hunodiwa hauna kukwana. Isu tinokurudzira kushandisa hupamhi calculator kuona ukobvu hwakakodzera uye ive nechokwadi chekugadzira dhizaini.
