Khulupirirani monga PCB wopanga mapangidwe tonsefe tiyenera kudziwa, nthawi iliyonse kapangidwe ka PCB kogwiritsa ntchito fakitole, nthawi zambiri amalandila mayankho a fakitale ya PCB, zambiri za EQ akatswiri ena amtunduwu samvetsa, ingoyankha, mutatha kugwiritsa ntchito matabwa am’mbuyo osagwiritsa ntchito, kufunafuna fakitale yamavuto, Wopanga board akhoza kukuyankhirani mu chiganizo chimodzi. Amangofuna kunena kuti, “Usachedwe, m’bale, chinthu ichi ndichofanana ndi kusaina ndi kupenta”. Ngati chilichonse chikalakwika, mudzayenera kudzudzula.

Chifukwa PCB mainjiniya ndi kilomita yomaliza yolumikizana ndi fakitale ya PCB board, nthawi zambiri amakhala akatswiri kubwerera poto, koma kubwerera kumbuyo, koma nthawi zina limakhaladi vuto lakapangidwe ka PCB, monga tawonetsera pansipa:

Vuto lamtunduwu silingayang’ane kudzera pakupanga mapulogalamu a EDA. Pakadali pano, nthawi zambiri timawona mindandanda yosiyanasiyana ya QA pa intaneti kuti tipewe vutoli.

Koma tikudziwa kuti ndi munthu kuti adzaze fomuyi, mpaka pamenepo, kuti zingakhale zovuta kuthana ndi vutoli, mainjiniya ena ndiomwe ali bwino kwambiri, aa cheke, koma mainjiniya ena kuti akonze, pali osayang’anitsidwa, “mbedza” yonse mpaka kumapeto, mavuto omwe amapangidwa kwambiri.

Kodi pali chida chomwe chimatha kusonkhanitsa zomwe zimatchedwa “mndandanda wazowerengera za PCB” kuti apange chida chodziwunika ndikuwunika? Lero ndikupangira chida chaching’ono cha DFM chosanthula mapulogalamu], chomwe chimachitadi zotere.

Chida ichi chili ndi ntchito zingapo zofunika:

1. Kusanthula ndikupanga mapulojekiti 20+ obisika

2. Chenjezo la zinthu zomwe zikukhudza mitengo, ndipo perekani mapulani okhathamiritsa zoopsa zobisika ndi zinthu zomwe zikukhudza mitengo

3, kuthandizira kuwunika kamodzi kokha kwa mitundu yonse ya mafayilo a Allegro, PADS, Altium, Protel, Gerber

4. Mipikisano wosanjikiza mbale basi likufanana dongosolo laminated

5, chida chanzeru cha impedance, chophatikizidwa ndi zinthu zopanga, kuwerengera deta ya impedance kapena kuwerengetsa kuwerengera.

6, bolodi mwakukonda kwanu, yachiwiri kupha bolodi yanthawi zonse kapena bolodi lapadera, dzenje losindikizira limatha kuwonjezeredwa.

7, kusanthula kozungulira komanso kofupikitsa (kusanthula kwa IPC network)

8. Dinani kamodzi pazida zopangira (Gerber, fayilo yolumikizira, mndandanda wa BOM)
