Wopanga PCB ndi PCBA wa Mafakitale
Ma PCBA a Zamalonda - Mabodi a Circuit a makina owongolera mafakitale
PCBA ya mafakitale, yomwe imadziwikanso kuti bolodi lowongolera mafakitale, ndi bolodi lozungulira lomwe limapangidwa kuti lipirire kugwedezeka, kugwedezeka, kutentha kwambiri, chinyezi, ndi fumbi m'zida zamafakitale. PCBA iyi imagwiritsidwa ntchito kuchita ntchito zambiri mumakampani owongolera mafakitale. Yapangidwa kuti ikhazikitse dera la polojekiti mwanjira yaying'ono, zomwe zimathandiza kuti magetsi aziyenda molondola munjira yofunikira ndikuwonjezera magwiridwe antchito azinthu. Mabolodi awa ndi ofunikira kwambiri pamapulojekiti ndi zida zowongolera mafakitale, zomwe zimathandiza kuyeza ndikusintha magawo ambiri a mzere wolumikizira, ndikupeza kuchuluka kolondola kwa thupi.
Kampani ya PCBA ya Zipangizo Zamakampani - Richpcba
Ngati mukufuna ma PCB/PCBA boards apamwamba kwambiri pamitengo yotsika mtengo, www.richpcba.com ndiye chisankho chanu chabwino kwambiri. Tinakhazikitsidwa ku Shenzhen, China mu 2004, ndife opanga ma PCB ang'onoang'ono omwe atumikira mabizinesi ambiri am'nyumba ndi akunja m'zaka zingapo zapitazi. Ntchito zathu zopangira sizimangokhala pa PCB ndi PCBA; timachitanso zofunikira zapadera, kukonzanso, ndi kusintha komwe makasitomala amapempha kuti akwaniritse zomwe akufuna. Kudzera mu ntchito zathu zaukadaulo komanso malingaliro athu odzipereka pantchito, tadziwika ndi opanga ambiri otsogola pantchito zamafakitale.
Timapanga ma PCB a mafakitale okhala ndi zigawo zambiri ndipo timapereka ntchito za PCBA zomwe zimayikidwa pamalo amodzi. Njira yathu imayamba ndi fayilo kapena Gerber yotumizidwa ndi wogwiritsa ntchito. Pambuyo polandira fayiloyi, mainjiniya athu amawunikanso ndikukhazikitsa njira yopangira kuti apange ma PCB board ndi zinthu za PCBA kuti azilamulira mafakitale pogwiritsa ntchito ukadaulo wosiyanasiyana. RICHPCBA imatha kukwaniritsa zofunikira za makasitomala pamapulojekiti osavuta mpaka ovuta, magulu ang'onoang'ono mpaka kusonkhanitsa ma PCB ambiri, komanso makampani atsopano mpaka makampani akuluakulu a mafakitale. Gulu lathu la akatswiri limachita mapulojekiti kudzera mwa oyang'anira mapulojekiti a 1V1, mothandizidwa ndi magulu ogula, uinjiniya, opanga, ndi oyang'anira khalidwe.

Zinthu Zokhudza Kupanga Ma PCB a Mafakitale
Kapangidwe ka Zigawo
Kuyika kwa zigawo pa bolodi ndi chinthu chofunikira kuganizira popanga ma PCB board owongolera mafakitale. Kuyika zinthu molakwika kungakhudze kudalirika ndi magwiridwe antchito a chinthu chomaliza. Pakupanga bolodi la PCB, chisamaliro chapadera chiyenera kutengedwa kuti zitsimikizire kuti zigawozo zayikidwa pa bolodi ndi malo osachepera 100 mils pakati pa m'mphepete mwa bolodi ndi zigawo zoyikidwa. Izi zimatsimikizira kuti miyeso ya bolodi ndi mabowo oyikidwa ndi ofanana.
EMI ndi RFI
Mu ntchito zamafakitale, ndikofunikira kuchepetsa zotsatira za Electromagnetic Interference (EMI) ndi Radio Frequency Interference (RFI), zomwe zingayambitse phokoso ndikusokoneza magwiridwe antchito a PCBA. Pachifukwa ichi, Rich PCBA imapereka njira zingapo:
Kapangidwe ka bolodi: Kuti muchepetse chiopsezo cha phokoso lolumikizana, lekanitsani ma circuit amphamvu kwambiri ndi ma circuit amphamvu kwambiri ndipo sungani zizindikiro kutali ndi magetsi ndi malo otsetsereka. Zizindikiro ziyenera kukhala zazifupi momwe zingathere, pomwe magetsi ndi malo otsetsereka ayenera kukhala akuluakulu momwe angathere ndipo aziyendetsedwa ndi mabowo otsika kuti achepetse kutsekeka kwa netiweki yamagetsi.
Zosefera: Onjezani zinthu zosefera monga ma capacitor ndi ma inductor ku magetsi ndi mizere yazizindikiro kuti muchotse phokoso losafunikira.
Njira Zotetezera Pansi ndi Kuteteza: Ikani zinthu zobisika m'makhola a Faraday kuti mulepheretse EMI ndi RFI.
Kusankha Zigawo: Sankhani zigawo za bolodi la dera zokhala ndi maziko abwino komanso zotchingira. Gwiritsani ntchito zingwe zotchingira kuti mulumikize bolodi ku zipangizo zakunja kuti mupewe kulumikizana kwa chizindikiro chosafunikira.
Zida za PCB Zowongolera Zamakampani
Kusankha zipangizo zopangira ma PCB ndikofunikira kwambiri ndipo kuyenera kutengera malo ogwirira ntchito. Zipangizo za ma PCB zomwe zimagwiritsidwa ntchito m'mafakitale ziyenera kukhala zotha kupirira mikhalidwe yovuta, monga kutentha kwambiri, magetsi ambiri, chinyezi, kugwedezeka, komanso kuwonetsedwa ndi mankhwala. Zina mwa zipangizo zomwe zimagwiritsidwa ntchito kwambiri pa ma PCB amafakitale ndi izi:
● Polyimide: Chipangizochi chogwira ntchito bwino kwambiri chimatha kupirira kutentha kwambiri mpaka 400°C ndipo nthawi zambiri chimagwiritsidwa ntchito poyendetsa ndege, usilikali, komanso mafakitale otentha kwambiri.
● Chomera chadothi: PCB ya ceramic imapangidwa ndi ceramic substrate ndi zitsulo. Ili ndi kutentha kwabwino kwambiri ndipo imatha kuthana ndi kutentha kwambiri komanso mankhwala oopsa. Amagwiritsidwa ntchito kwambiri pamagetsi amphamvu komanso kugwiritsa ntchito pafupipafupi kwambiri.
● PTFE: PTFE kapena polytetrafluoroethylene ndi fluoropolymer yokhala ndi mphamvu zabwino kwambiri zamagetsi zomwe zimatha kupirira kutentha kwambiri mpaka 260°C. Imagwiritsidwa ntchito kwambiri m'malo ogwiritsidwa ntchito pafupipafupi komanso m'ma microwave, komanso m'malo ovuta okhala ndi mankhwala.
● FR-4: Zipangizo zopangidwa ndi nsalu yolukidwa ya fiberglass ndi epoxy resin ndizomwe zimagwiritsidwa ntchito kwambiri pa ma PCB ambiri, kuphatikizapo mafakitale. FR4 PCB ili ndi mphamvu zabwino zotetezera magetsi ndipo imatha kupirira kutentha kwambiri komanso mankhwala.
