Mune ino blog, isu tichaongorora zvinhu zvinokanganisa kuomarara uye kuchinjika PCB mutengo wekusimudzira yako redunhu bhodhi kugadzirwa uye optimize yako yedunhu bhodhi kugadzira mutengo.
Mabhodhi edunhu akadhindwa (PCBs) chikamu chakakosha chezvinenge zvese zvemagetsi zvatinoshandisa nhasi. Ingave yedu smartphones, malaptop, kana kunyange midziyo yemumba, maPCB anoita basa rakakosha mukupa kubatana uye kusimbisa zvishandiso izvi. Nekudaro, mutengo wekugadzira PCB unogona kusiyana zvichienderana nemhando dzakasiyana siyana.
Dhizaini yakaoma:
Chimwe chezvinhu zvikuru zvinokanganisa mutengo wePCB dhizaini yakaoma. Iyo yakanyanya kuoma dhizaini, iyo yakakwira mutengo wekugadzira. Madhizaini akaomarara anowanzoda epamberi uye akaomarara wedunhu, izvo zvinoda hunyanzvi hwekugadzira matekiniki uye imwe nguva yekuwedzera. Naizvozvo, dhizaini yakaoma inofanirwa kutariswa kana uchifungidzira mutengo wePCB.
Kusarudzwa kwezvinhu:
Chimwe chinhu chakakosha chinokanganisa mutengo wePCB isarudzo yezvinhu. Rigid PCBs anowanzo kugadzirwa achishandisa FR-4, chinhu chinoshandiswa zvakanyanya chinodzora murazvo chine zvinhu zvakanaka zvekupisa uye zvemagetsi. Nekudaro, pane misiyano mumhando uye ukobvu hweFR-4, izvo zvinogona kukanganisa mutengo wese wePCB. Flexible PCBs, kune rumwe rutivi, shandisa inoshanduka substrate zvinhu senge polyimide. Zvinhu izvi zvinodhura kupfuura FR-4, zvichikonzera mutengo wepamusoro wePCB inoshanduka.
Saizi yebhodhi uye nhamba yezvikamu:
Saizi uye nhamba yezvikamu zvePCB inoitawo basa rakakosha pakuona mutengo wayo. Mabhodhi mahombe kana mapuranga ane zvidimbu zvakawanda zvinoda zvimwe zvinhu uye nguva yekugadzira, zvichikonzera kuwedzera kwemitengo. Pamusoro pezvo, kugadzira mabhodhi akakura kungangoda hunyanzvi hwekushandisa uye zvivakwa, zvichiwedzera kukanganisa mutengo wese. Izvo zvakakosha kuenzanisa saizi uye layer zvinodiwa neinodiwa mashandiro kuti uwedzere mutengo.
Component density:
Kuwanda kwezvikamu paPCB kunokanganisa zvakananga mutengo wayo wekugadzira. Higher component density inoreva kuti zvimwe zvikamu zvakarongedzerwa munzvimbo diki, zvichikonzera nzira yakaoma kunzwisisa uye zvidiki zvidiki. Kuwana yakakwira chikamu density kazhinji kunoda epamberi ekugadzira matekiniki akadai se microvia drilling uye akaturikidzana vias, izvo zvinowedzera mutengo wese wePCB. Naizvozvo, zvakakosha kurova chiyero pakati pechikamu density uye mutengo kuti uve nechokwadi chekushanda kwakakwana pasina kukanganisa zvakanyanya pamutengo.
Nhamba yemakomba:
Kuchera makomba chikamu chakakosha chePCB kugadzira sezvo ivo vanofambisa kubatana kweakasiyana akaturikidzana uye chikamu chinokwira kuburikidza vias. Nhamba uye saizi yemakomba akacherwa anokanganisa zvakanyanya mari yekugadzira. Makomba ekuchera akakura uye madiki, mapofu kana kuvigwa vias, uye microvias zvese zvinokonzeresa kuwedzera mari nekuda kwekuwedzera nguva uye kuoma kunodiwa nekuchera maitiro. Kuti uchengetedze chiyero pakati pekushanda uye mutengo, nhamba uye rudzi rwemaburi ekuchera zvinofanira kunyatsotariswa.
Surface treatment:
Kugadzirira kwepamusoro inhanho yakakosha mukugadzira PCB kuchengetedza mhangura kubva kune oxidation uye kuve nechokwadi chekutengesa. Pane nzira dzakasiyana dzekurapa dzepamusoro dziripo dzakadai seHASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold) uye OSP (Organic Solderability Preservative). Imwe neimwe nzira yekugadzirira yepasi ine mutengo wakasiyana wakabatana, unonyanya kutsanangurwa nezvinhu uye zvevashandi zvinodiwa. Paunenge uchisarudza iyo chaiyo yepamusoro pekupedzisira yePCB yako, zvakakosha kuti uongorore inodiwa mashandiro uye bhajeti.
Nhamba yekuraira:
PCB odha huwandu hunokanganisa mutengo wese. Huru hwekuraira huwandu hunowanzo konzera hupfumi hwechiyero, uko mari yekugadzira mayuniti inoderedzwa. Izvi zvinodaro nekuti vagadziri vanogona kukwirisa maitiro avo ekugadzira, kuderedza mitengo yekuseta uye kugadzirisa mashandiro emaodha akawanda. Kune rimwe divi, maodha madiki anogona kuunza imwe mari yekuseta uye yekugadzira, zvichiita kuti idhure. Naizvozvo, kuisa maodha akakura kunobatsira kuderedza mutengo wePCB.
Supplier sarudzo:
Kusarudzwa kwemupi wePCB kwakakosha kuve nechokwadi chemhando uye mutengo-kushanda. Vatengesi vakasiyana vanogona kuve nemhando dzakasiyana dzemitengo zvichienderana nehunyanzvi hwavo, zvishandiso, uye kugona kugadzira. Izvo zvakakosha kuti utsvage uye uongorore vangangove vatengesi, uchifunga nezvezvinhu zvakaita semukurumbira wavo, zvitupa, maitiro ekutonga kwemhando uye ongororo yevatengi. Kushanda nevatengesi vanovimbika uye vane ruzivo kunobatsira kuwana chiyero chakakodzera pakati pemutengo uye mhando.
Muchidimbu
Pane zvinhu zvakati wandei zvinokanganisa mutengo weakaomarara uye anochinjika maPCB.Dhizaini yakaoma, kusarudzwa kwezvinhu, saizi yebhodhi, density yechikamu, huwandu hwemakomba ekuchera, kupedzisa kwepamusoro, huwandu hweodha uye kusarudzwa kwevatengesi zvese zvinokanganisa mutengo wakakwana. Nekunyatsofunga nezvezvinhu izvi uye kurova chiyero pakati pekushanda uye zvehupfumi, vagadziri vemagetsi vanogona kukwidziridza mutengo wePCB uku vachiona yemhando yepamusoro uye kushanda kwezvigadzirwa zvavo.
