Ma PCB kapena matabwa osindikizidwa ndi gawo lofunikira pamagetsi amakono.Ma PCB amagwiritsidwa ntchito m'chilichonse kuyambira zoseweretsa zazing'ono mpaka pamakina akuluakulu amakampani.Ma board ang'onoang'ono ozungulirawa amathandizira kupanga mabwalo ovuta mu mawonekedwe ophatikizika.Mitundu yosiyanasiyana ya ma PCB amapangidwira ntchito zosiyanasiyana.Mu blog iyi, tikambirana mitundu ina ya PCB yomwe imagwiritsidwa ntchito.Pansipa pali mitundu yonse ya PCB yochokera ku ABIS Circuits.
1. single sided kusindikizidwa dera bolodi
PCB ya mbali imodzindiye mtundu wofunikira kwambiri wa PCB.Amakhala ndi mzere umodzi, wopangidwa ndi zitsulo zamkuwa kumbali imodzi ya bolodi ndi chitetezo kumbali inayo.Mitundu iyi ya ma PCB ndi otchuka mumakampani opanga zamagetsi chifukwa amagwiritsidwa ntchito pamabwalo osavuta ndipo ndi otsika mtengo kupanga.
2. mbali ziwiri zosindikizidwa dera bolodi
Ma PCB a mbali ziwirindizovuta kwambiri kuposa ma PCB osanjikiza amodzi.Amakhala ndi zizindikiro zamkuwa kumbali zonse za bolodi.Zigawo ziwirizo zimalumikizidwa pogwiritsa ntchito vias, zomwe ndi mabowo ang'onoang'ono obowoleredwa mu bolodi.Ma PCB a mbali ziwiri amagwiritsidwa ntchito m'makompyuta, zida zomvera, ndi magetsi.
3. bolodi lamitundu yambiri
Ma PCB ambirindizovuta kwambiri kuposa ma PCB a mbali imodzi kapena awiri ndipo ali ndi zigawo zingapo zamkuwa.Zigawozo zimatetezedwa ku wina ndi mzake ndi dielectric zakuthupi, ndipo zigawozo zimagwirizanitsidwa ndi vias.Ma PCB amtunduwu amagwiritsidwa ntchito pazantchito zapamwamba monga mafoni am'manja, mapiritsi, ndi zinthu zina zapamwamba kwambiri.
4. bolodi losinthasintha ladera
Ma PCB osinthikaamapangidwa kuchokera ku zinthu zosinthika monga polyamide kapena polyester.Amakhala osinthasintha kotero kuti amatha kupindika mosavuta popanda kuwononga bolodi lozungulira ndipo amagwiritsidwa ntchito ngati makhadi okumbukira ndi zowonetsera za LCD.
PCB yosasunthika imaphatikiza kusinthasintha kwa PCB yosinthika ndi kukhazikika kwa PCB yolimba.Amapangidwa kuchokera kuzinthu zosinthika komanso zolimba, zomwe zimawapangitsa kukhala oyenera kugwiritsa ntchito zomwe zimafuna kusinthasintha komanso kukhazikika.
Palinso mitundu ina ya ma PCB mongaHDI (High Density Interconnect) PCBs,Aluminium PCBs, Ceramic PCBs, etc.Mtundu uliwonse wa PCBili ndi mawonekedwe ake apadera ndipo idapangidwa kuti igwiritsidwe ntchito mwapadera.
Mwachidule, ma PCB ndi gawo lofunikira pamakampani opanga zamagetsi ndipo asintha momwe timakhalira.Mitundu yosiyanasiyana ya ma PCB imalola kusinthasintha, kulondola, ndikuwongolera kapangidwe ka dera, zomwe zimatsogolera kupita patsogolo kwaukadaulo.Pomvetsetsa mitundu yosiyanasiyana ya PCB, mutha kusankha yomwe ikugwirizana ndi pulogalamu yanu ndikuwongolera magwiridwe antchito.
