Mkuwa wolimba PCB produce 4 or more ounces of copper on each layer. Four ounce copper PCBS are most commonly used in commercial products. Mchere ungakhale wokwera mpaka ma ola 200 pa phazi lalikulu. Lolemera mkuwa PCBS amagwiritsidwa ntchito kwambiri pamagetsi ndi ma circuits omwe amafunikira kufalitsa kwamphamvu kwamphamvu. In addition, the thermal strength these PCBS provide is impeccable. M’magwiritsidwe ambiri, makamaka zamagetsi, matenthedwe amafunikira chifukwa kutentha kumawononga zinthu zamagetsi zamagetsi ndipo zimakhudza magwiridwe antchito am’madera.

Kutaya kutaya mphamvu & GT; Ma PCBS amkuwa olemera kwambiri kuposa PCBS wamba. Heat dissipation is critical to developing robust circuits. Kukonza ma siginidwe osayenera sikungakhudze magwiridwe antchito azida zamagetsi, komanso kufupikitsa moyo wautumiki wa dera.

Magetsi oyendetsa magetsi amatha kupangika pogwiritsa ntchito ma PCBS amkuwa akulu. Njira yolumikizira ma wayayi imathandizira kuthana ndi matenthedwe ndipo imatha kumaliza bwino ndikuphatikiza njira zingapo pa mbale imodzi yaying’ono.

Ma PCBS olimba amkuwa amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana chifukwa amapereka ntchito zosiyanasiyana kuti magwiridwe antchito azisangalatsa. These PCBS are widely used in high-power equipment such as transformers, radiators, inverters, military equipment, solar panels, automotive products, welding equipment and power distribution systems.

Lolemera mkuwa PCB kupanga

Monga momwe zilili ndi PCBS yokhazikika, ma PCBS amkuwa olemera amafunikira kukonzanso kwina.

Ma PCBS amtundu wamkuwa olemera amapangidwa pogwiritsa ntchito ukadaulo wakale, zomwe zimapangitsa kuti anthu azitsata mosagwirizana pa PCB, zomwe zimapangitsa kuti zisayende bwino. Today, however, modern manufacturing techniques support fine cuts and minimal bottom cuts.

Matenthedwe othandizira kupsinjika kwa PCB yamkuwa yolemera

Zinthu monga kutentha kwamafuta ndizofunikira pakupanga ma circuits ndipo mainjiniya ayenera kuzichotsa momwe angathere.

Popita nthawi, njira zopangira PCB zasintha, ndipo maukadaulo osiyanasiyana a PCB apangidwa, monga aluminium PCBS, yokhoza kuthana ndi kupsinjika kwamafuta.

Ndimachita chidwi ndi opanga ma PCB amkuwa olemera kuti azigwiritsa ntchito kutentha komanso kapangidwe kazachilengedwe kwinaku akuchepetsa bajeti yamagetsi posunga madera.

Chifukwa kutenthedwa kwa zida zamagetsi kumabweretsa kulephera, ngakhale kuyika moyo pachiswe, kuwongolera zoopsa sikunganyalanyazidwe.

The traditional process for achieving heat dissipation quality is to use an external heat sink, connected to the heating component. Popeza, popanda kutaya kwanyengo, gawo lotenthetseralo limayandikira kutentha kwambiri, kutulutsa kutentha uku, rediyeta imagwiritsa ntchito kutentha kuchokera pagawolo ndikulipititsa m’malo ozungulira. Usually, these radiators are made of copper or aluminum.The use of these radiators not only exceeded the development cost, but also required more space and time. Zotsatira zake, sizimayandikira pafupi ndi mphamvu yozizira ya PCB yamkuwa yolemera.

Mu PCBS yamkuwa yolemera, koziziritsira kumalowetsedwa mu bolodi popanga, m’malo mogwiritsa ntchito kutentha kwakunja. As the external radiator requires more space, there are fewer restrictions on the placement of the radiator.

Chifukwa choziziritsira chimakutidwa ndi bolodi ladela ndikulumikizidwa ndi gwero lotentha pogwiritsa ntchito mabowo m’malo mogwiritsa ntchito polumikizira ndi malumikizidwe amakanika, kutentha kumasamutsidwa mwachangu, komwe kumapangitsa nthawi yotaya kutentha.

Matenthedwe obowolera mu PCBS amkuwa amathandizira kutentha kwambiri kuposa matekinoloje ena, chifukwa matenthedwe oyenda-mabowo amapangidwa ndi mkuwa. Kuphatikiza apo, makulidwe apano amakula bwino ndipo khungu limachepetsedwa.

Ubwino katundu mkuwa PCB:

Ubwino wa PCB yamkuwa yolemetsa imapangitsa kukhala kofunikira kwambiri pakukula kwamphamvu yamagetsi. Ndende yayikulu yamkuwa imatha kuthana ndi mphamvu yayikulu komanso kutentha kwakukulu, ndichifukwa chake ma circuits amphamvu apangidwa pogwiritsa ntchito ukadaulo uwu. Ma circuits oterewa sangathe kupangidwa ndi ma PCBS otsika kwambiri amkuwa chifukwa sangathe kulimbana ndi kupsinjika kwamphamvu komwe kumachitika chifukwa champhamvu zamagetsi. Ma PCBS olimba amkuwa amawerengedwa kuti ndi ma PCBS amakono kwambiri chifukwa champhamvu yozizira.

Mgwirizano wapakati pakulimba kwamkuwa ndi wamakono ndichofunikira pakugwiritsa ntchito PCB yamkuwa yolemera. Pamene mkuwa ukuwonjezeka, momwemonso gawo lonse lamkuwa lamkuwa, lomwe limachepetsa kukana kwa dera. Monga tikudziwa, kutayika kumawononga kapangidwe kalikonse, ndipo kusungunuka kwa mkuwa kumathandizira ma PCBS awa kuti achepetse ndalama zamagetsi.

Zochita pakadali pano ndizofunikira, makamaka pochita ndi ma siginecha amagetsi, ndipo magwiridwe antchito amakono a PCBS yamkuwa amathandizidwa ndi kukana kwawo pang’ono.

Zolumikizira ndizofunikira pakulumikiza kwa jumper. However, connectors are often difficult to maintain on traditional PCBS. Chifukwa cha kuchepa kwamphamvu kwa PCBS kwakanthawi, cholumikizira nthawi zambiri chimakhudzidwa ndi kupsinjika kwamakina, koma PCBS yamkuwa yolemera imapereka mphamvu yayikulu ndikuonetsetsa kuti ndiyodalirika kwambiri.

RAYMING wa katundu mkuwa PCB kupanga

Kulemera kwakukulu kwa PCB kumafuna chisamaliro choyenera, ndipo kusayendetsa bwino popanga kumatha kuyambitsa magwiridwe antchito, nthawi zonse lingalirani ntchito za wopanga waluso.

RAYMING imapereka zida zopangira ma PCB zamitundu yonse ya PCBS. RAYMING wakhala okhazikika kupanga katundu mkuwa PCB ndikupanga zithunzi zapamwamba kwambiri pazaka khumi zapitazi.

Lolemera PCBS yamkuwa amapangidwa pamakina otsogola otsogola, omwe amatipangitsa kuti tikhale ndi PCBS zodalirika kwambiri. Pakadali pano, tapanga ma PCBS osanjikiza awiri mpaka ma oun 20, ma PCBS angapo okhala ndi masekeli 4-6 amkuwa.
