Kwihlabathi le-elektroniki, iibhodi zesekethe eziprintiweyo (i-PCBS) zizinto ezisisiseko ezisebenza njenge-backnene yezixhobo ezininzi ze-elektroniki. Inkqubo yemveliso yezi bhodi inzima ibandakanya amanyathelo amaninzi, enye yezona zigxeki zibaluleke kakhulu. Ukukhetha iBhodi yeShekeji eprintwe iprintwe iprintweyo ibaluleke kakhulu kukwandisa ukusebenza ngokukuko nokuqinisekisa umgangatho wemveliso yokugqibela. Eli nqaku liza kukukhokela ngezinto eziphambili ekufuneka ziqwalaselwe xa ukhetha i-PCB ye-PCB kancinci kwiimfuno zakho zeBhodi yeBhodi yeSiphaluka.
Ukuqwalaselwa okukhulu ngokukhetha
1. I-Drill ubukhulu be-bit: ubungakanani be-drill bit ibaluleke kakhulu. Kufuneka ihambelane neenkcazo zecandelo elibekwe kwi-PCB. Ubungakanani bomgangatho wobungakanani busuka kwi-0.2 mm ukuya kwi-3.2 mm, kodwa ubungakanani bezikolo kukwafumaneka kwizicelo ezizodwa.
2. Izinto ezibonakalayo: Izixhobo ezahlukeneyo ze-PCB zifuna iibits ezahlukeneyo. Umzekelo, i-Geber-fiber ye-Giber eqinileyo enje nge-Fr-4 isenokufuna i-Darbide ye-carbide ye-carbide, ngelixa izinto ezithambileyo zinokuthathwa nge-HSS.
I-3. Isantya sokuqhuba: Isantya sokuntywila kuchaphazela umgangatho womngxunya ophumileyo. Izantya ngokukhawuleza zisebenza ngakumbi, kodwa zinokunyusa umngcipheko wokonakalisa i-PCB. Kubalulekile ukufumana ibhalansi efanele ilungele iimfuno zakho zokuqhuba.
4. Ukupholisa kunye nokuthambisa: ukuqhuba kuvelisa ubushushu, onokwenzakalisa i-Drill bit kunye ne-PCB. Sebenzisa inkqubo yokupholisa okanye ukuthambisa kunokunceda ukugcina ubushushu obufanelekileyo kwaye wandise ubomi bendawo ye-Drill.
I-5. Ixabiso le-vs. Umgangatho: Ngelixa kunokuhendela ukukhetha ukhetho oluthe ngxi, utyalomali kumgangatho ophezuluIbhodi yeBhodi ye-PCBUngasindisa imali ekuhambeni kwexesha. Umgangatho we-rill bits unciphise umngcipheko wokwahlukana kwaye uqinisekise ngemingxunya yokucoca, okukhokelela kwiziphene ezimbalwa kwimveliso yokugqibela.
Ukuququmbela
Ukukhetha eyona iprintiweyoIbhodi yesekethe iqhubaIncinci inyathelo elibalulekileyo kwinkqubo yemveliso yePCB. Ngokuqonda iindidi ze-bits ezikhoyo ezikhoyo kwaye ziqwalasele izinto ezinje ngobungakanani, ukwenziwa kwezinto ezibonakalayo, nokuthathwa kwesantya, unokuqinisekisa iziphumo ezisemgangathweni. Nokuba uyingcali ye-hobbydist okanye ingcali kushishino lwe-elektroniki, ukwenza ukhetho olunolwazi lweBhodi yeBhodi yeBhodi yeBhodi iya kuthi ekugqibeleni iphucule ukusebenza kunye nokuthembeka kwezixhobo zakho ze-elektroniki.
