Kuwongolera kwamafuta mu ma rigid flex circuit board

Mu blog iyi, tiwona mfundo zazikuluzikulu za kasamalidwe ka matenthedwe a ma board ozungulira okhazikika komanso chifukwa chomwe akuyenera kuyankhidwa panthawi yopanga ndi kupanga.

Popanga ndi kupanga matabwa ozungulira ozungulira, kayendetsedwe ka kutentha ndi chinthu chofunika kwambiri chomwe sichinganyalanyazidwe.Ma board ozungulira ovuta komanso osunthikawa akuchulukirachulukira m'mafakitale osiyanasiyana chifukwa cha kuthekera kwawo kuphatikiza kusinthasintha kwa mabwalo osinthika ndi kulimba komanso kudalirika kwa mabwalo olimba.Komabe, kapangidwe kake kapadera kamapangitsanso zovuta pakuwongolera kutentha kwapang'onopang'ono ndikuwonetsetsa kuti zikuyenda bwino.

Chimodzi mwazofunikira pakuwongolera kutentha kwa ma board ozungulira okhazikika ndikusankha zigawo ndi kuyika.Kukonzekera kwa zigawo pa bolodi la dera kungakhudze kwambiri kutentha kwa kutentha.Zida zotenthetsera ziyenera kuyikidwa bwino kuti zichepetse kutentha m'malo enaake.Izi zimaphatikizapo kusanthula mawonekedwe a kutentha kwa chigawo chilichonse ndikuganizira zinthu monga kutaya mphamvu, mtundu wa phukusi ndi kukana kutentha.Mwa kufalitsa zigawo zopangira kutentha ndikugwiritsa ntchito bwino ndege zamkuwa kapena matenthedwe, opanga amatha kupititsa patsogolo ntchito zamatenthedwe ndikuletsa malo otentha.

Chinthu chinanso chofunika kwambiri pa kayendetsedwe ka kutentha kwa ma rigid-flex circuit board ndi kusankha zinthu.Kusankhidwa kwa gawo lapansi ndi laminate kungakhudze kwambiri matenthedwe matenthedwe komanso kutentha kwathunthu.Kusankha zida zokhala ndi matenthedwe apamwamba kwambiri, monga ma laminates amkuwa, kumatha kupititsa patsogolo kutentha kwa bolodi lanu ladera.Kuphatikiza apo, kusankha gawo lapansi lomwe lili ndi gawo locheperako la kukulitsa kwamafuta kumatha kuchepetsa kupsinjika pazigawo panthawi yanjinga yotentha, potero kuchepetsa chiopsezo cholephera.Kusankha zinthu moyenera kuyeneranso kuganiziranso zinthu zina monga kukhazikika, kusinthasintha komanso kugwirizana ndi njira zopangira.

Mapangidwe a geometry board board onse ndi masanjidwe ake amakhalanso ndi gawo lofunikira pakuwongolera kutentha.Kuyika kwazitsulo zamkuwa, ndege zamkuwa, ndi njira zotenthetsera ziyenera kuganiziridwa mosamala kuti zithetse kutentha.Okonza ayenera kukhala ndi cholinga chokwaniritsa kugawa bwino kwa mkuwa kuti azichita bwino kutentha kutali ndi zigawo zofunika kwambiri.Kupewa kupendekera kocheperako komanso kugwiritsa ntchito njira zokulirapo zamkuwa kumatha kuchepetsa kukana ndipo motero kumachepetsa kutentha kwamphamvu.Kuonjezera apo, kuwonjezera mapepala otentha mozungulira zigawo zomwe zimafuna kutentha kowonjezera kungathandize kusunga kutentha kwabwino.

Mbali yomwe nthawi zambiri imanyalanyazidwa pa kayendetsedwe ka kutentha kwa ma rigid-flex circuit board ndikuganizira za malo ogwirira ntchito.Kumvetsetsa za chilengedwe chomwe gulu la dera lidzakumana nalo ndikofunikira kwambiri kuti apange njira zoyendetsera bwino zoyendetsera kutentha.Zinthu monga kutentha kozungulira, chinyezi, ndi kayendedwe ka mpweya ziyenera kuganiziridwa.Kuyerekeza ndi kuyesa kwa kutentha kungapereke chidziwitso chofunikira cha momwe bolodi idzagwirira ntchito pansi pazigawo zosiyanasiyana zogwirira ntchito, kulola okonza kupanga kusintha kofunikira kuti akwaniritse bwino ntchito yotentha.

Kuwongolera kwamafuta kuyenera kuganiziridwanso panthawi yopanga ma board ozungulira olimba.Njira zophatikizira bwino, kuphatikiza zowotchera ndi kuyika zinthu moyenera, zimathandizira kwambiri kuti matenthedwe agwire bwino ntchito.Kuwonetsetsa kukhudzana kosalekeza ndi kodalirika kwachitsulo ndi chitsulo pakati pa gawo lotenthetsera ndi bolodi ladera ndikofunikira kuti kutentha kuyendetse bwino.Kusankhidwa koyenera kwa phala la solder, mbiri ya reflow, ndi zida zolumikizirana zogwirizana zonse zimathandizira kukwaniritsa zolinga zomwe mukufuna.

Powombetsa mkota,kasamalidwe ka matenthedwe ndikofunikira kwambiri popanga ndikupanga ma board ozungulira okhazikika.Kuwongolera koyenera kwamafuta kumakulitsa moyo wa board board, kumalepheretsa kulephera kwamagulu, ndikuwonetsetsa kuti magwiridwe antchito odalirika.Kusankha mosamala zigawo, kusankha zinthu, geometry board board, ndikuganizira malo ogwirira ntchito ndi zinthu zofunika kwambiri pakukwaniritsa kasamalidwe kodalirika ka kutentha.Pothana ndi zovuta izi panthawi yopangira ndi kupanga, mainjiniya amatha kupanga ma board ozungulira okhazikika omwe amakwaniritsa zofunikira zamafuta omwe amafunidwa ndikupereka magwiridwe antchito apamwamba.
