Ndizodziwika bwino kuti zikwangwani zozungulira (Ma PCB) ndi gawo limodzi mwazida zonse zamagetsi zamagetsi zamagetsi zamagetsi. Mitundu ingapo yama PCB imapezeka m’mitundu ndi zigawo zosiyanasiyana, kutengera zofunikira pakufunsira. PCB ikhoza kukhala nayo kapena ingakhale yopanda chitsulo. Ma PCB ambiri achitsulo amapangidwa ndi aluminiyamu, pomwe ma PCB amtunduwu amapangidwa ndi magawo osakhala achitsulo monga ceramic, pulasitiki, kapena fiberglass. Chifukwa cha momwe amamangidwira, pali kusiyana pakati pa mbale za aluminium ndi ma PCB wamba. Chabwino ndi chiyani? Mwa mitundu iwiri ya PCB yomwe ikugwirizana ndi zofunikira zanu? Tiyeni tipeze chinthu chomwecho pano.

Kuyerekeza ndi chidziwitso: Aluminium motsutsana ndi ma PCB wamba

Poyerekeza aluminiyumu ndi ma PCB wamba, ndikofunikira kuti muziganizira kaye zofunikira pamagwiritsidwe anu poyamba. Kuphatikiza pakupanga, kusinthasintha, bajeti, ndi zina, ndizofunikanso. Chifukwa chake, nayi zina zambiri pama PCB oyenera ndi a aluminium kukuthandizani kudziwa PCB yomwe mukufuna.

Zambiri za ma PCB wamba

Monga dzinalo likunenera, ma PCB wamba amapangidwa munjira yofananira kwambiri komanso yogwiritsidwa ntchito kwambiri. Ma PCB awa nthawi zambiri amapangidwa kuchokera ku magawo a FR4 ndipo amakhala ndi makulidwe ofanana a 1.5mm. Ndizotsika mtengo kwambiri ndipo zimakhala ndi kulimba kwapakatikati. Popeza zida za gawo lapansi za ma PCB oyendetsa bwino ndizoyendetsa bwino, ali ndi lamination yamkuwa, filimu yotsekemera, komanso kusindikiza pazenera kuti zizikhala zoyenda. Izi zitha kukhala zosakwatiwa, ziwiri, kapena zingapo. Zipangizo zamtundu umodzi zokha monga zida zowerengera. Zipangizo zosanjikiza zimagwiritsidwa ntchito pazinthu zovuta kuzilumikiza, monga makompyuta. Chifukwa chake, kutengera kuchuluka kwa zida ndi zigawo zomwe agwiritsa ntchito, amagwiritsidwa ntchito pazinthu zambiri zosavuta komanso zovuta. Ma mbale ambiri a FR4 satenthedwa ndi kutentha kapena kutentha, chifukwa chake kutentha kwachindunji kuyenera kupewedwa. Zotsatira zake, amakhala ndi maenje otenthetsera kapena mabowo odzaza amkuwa omwe amalepheretsa kutentha kulowa mdera. Mutha kupewa kugwiritsa ntchito ma PCB oyenera ndikusankha ma PCBS a aluminium pomwe kutentha sikufunika kuti muzichita kutentha kwambiri. Komabe, ngati zosowa za pulogalamu yanu ndizokhazikika, mumayikidwa bwino kuti musankhe ma PCB a fiberglass omwe ndiwothandiza komanso osungira ndalama.

Pali zambiri zambiri za aluminium PCB

Aluminiyamu PCB ili ngati PCB ina iliyonse yomwe aluminiyamu imagwiritsidwa ntchito ngati gawo lapansi. Amagwiritsidwa ntchito kwambiri pamafunso ambiri ogwira ntchito m’malo ovuta komanso kutentha kwambiri. Koma sagwiritsidwa ntchito pamapangidwe ovuta omwe amafunikira zigawo zambiri kuti aikidwe. Aluminium ndi woyendetsa wabwino wa kutentha. Komabe, ma PCB awa akadali ndi makina osindikizira, amkuwa ndi osakanikirana. Nthawi zina zotayidwa zimatha kugwiritsidwa ntchito ngati gawo limodzi molumikizana ndi magawo ena osagwira, monga ulusi wamagalasi. Aluminiyamu PCB imakhala yosakwatira kapena iwiri. Nthawi zambiri samakhala ndi mizere ingapo. Chifukwa chake, ngakhale ali otentha, kuyala kwa ma PCB a aluminiyamu kumabweretsa zovuta zake. Amagwiritsidwa ntchito kwambiri pakuunikira kwa panja ndi panja kwa LED. Ndi zolimba ndipo zimathandiza kuchepetsa kukhudzidwa kwa chilengedwe.
