indlela yokwenza isekethe pcb

I-PCB (iBhodi yeSekethe eShicileleyo) sisiseko sezixhobo zombane, ezivumela uqhagamshelo kunye nokuhamba kombane phakathi kwamacandelo ahlukeneyo.Nokuba ungumntu othanda izinto zombane okanye ulichule, ukwazi ukwenza iisekethe zePCB sisakhono esibalulekileyo esinokuphucula iiprojekthi zakho zobugcisa.Kule bhlog, siza kubonelela ngenyathelo ngenyathelo isikhokelo sendlela yokwenza isekethe yePCB.

1. Uyilo kunye noyilo lwesicwangciso:

Inyathelo lokuqala ekwenzeni isekethe yePCB kukuyila kunye nokudala iskimu.Ukusebenzisa isoftware yoyilo lweskimu, efana noKhozi okanye iKiCad, zoba umzobo wesekethe.Ukubekwa ngononophelo kwamacandelo, uyilo olufanelekileyo oluqinisekisa ukuhamba kwengqiqo yemiqondiso kunye nomzila osebenzayo kubalulekile.

2. Uyilo lwePCB:

Nje ukuba iskimu sigqityiwe, inyathelo elilandelayo kukwenza ubeko lwePCB.Le nkqubo ibandakanya ukudluliselwa kwamacandelo kunye noqhagamshelo ukusuka kwiskim ukuya kuyilo lwebhodi ebonakalayo.Lungelelanisa amacandelo kunye neepakethe zawo, uqinisekisa ukuqhelaniswa okufanelekileyo kunye nokugcina isithuba esisiso ukuthintela ukuphazamiseka.

3. Ukukrolwa kwepleyiti:

Nje ukuba ubeko PCB lugqityiwe, lixesha lokuba etch ibhodi.Qala uprinte uyilo lwebhodi yesekethe kwiphepha elikhethekileyo lokudlulisa usebenzisa iprinta yelaser.Beka ushicilelo kwi-PCB enengubo yobhedu kwaye uyitshise ngentsimbi okanye i-laminator.Ubushushu buhambisa i-inki ukusuka kwiphepha ukuya ebhodini, ukwenza umaleko okhuselayo kwiindlela zobhedu.

4. Inkqubo yokufaka:

Nje ukuba udluliselo lugqityiwe, lixesha lokumisa ibhodi.Lungiselela isitya kunye nesisombululo esifanelekileyo sokutshiza (njenge-ferric chloride) kwaye udibanise ibhodi kuyo.Gcoba ngobumnene isisombululo sokususa ubhedu obuninzi kwiindawo ezingakhuselekanga, ushiye kuphela imikhondo efunwayo.Ngexesha lale nkqubo, qiniseka ukuba uthathe amanyathelo okhuseleko afana nokunxiba iiglavu kunye nezibuko, njengoko isisombululo se-etching sinokuba yingozi.

5. Ukugrumba:

Emva kwe-etching, imingxuma kufuneka igrunjwe ukuze kubekwe amacandelo.Sebenzisa i-drill enentwana encinci ehambelana nobukhulu becandelo elikhokelela.Gcoba ngononophelo kwiindawo ezichongiweyo zecandelo kwaye uqinisekise ukuba imingxuma icocekile kwaye ayinayo nayiphi na inkunkuma.

6. Ukuwelda:

Emva kokuba ibhodi iye yachongwa kunye nemingxunya yombiwa, lixesha lokuthengisa izinto kwiPCB.Qala ngokudibanisa amacandelo kwimingxunya yawo, uqinisekise ukuba ahleli ngokukhuselekileyo.Flip ibhodi phezu kwaye uthengise icandelo ngalinye, usebenzisa ubushushu ukunyibilikisa ucingo lwe-solder kwaye wenze ibhondi eyomeleleyo.Sebenzisa umgangatho we-soldering iron kunye ne-flux ukuze ufezekise i-solder ecocekileyo, ethembekileyo.

7. Uvavanyo:

Emva kokuthengisela onke amacandelo, ukusebenza kwesekethe kufuneka kuvavanywe.Sebenzisa i-multimeter ukujonga ukuqhubeka kunye nokuqinisekisa uqhagamshelwano olufanelekileyo.Kwakhona, yenza uhlolo olubonakalayo ukuze uqiniseke ukuba akukho zibhulorho ze-solder okanye iindawo ezibandayo.

ukuququmbela:

Ukudala iisekethe zePCB kunokubonakala kunzima ekuqaleni, kodwa ngolwazi oluchanekileyo kunye nezixhobo, kunokuba ngumsebenzi onokufezekiswa.Ngokulandela inyathelo ngenyathelo isikhokelo esinikwe kule bhlog, unokwenza ngokuzithemba iisekethe zePCB kwiiprojekthi zakho zombane.Khumbula, ukuziqhelanisa kwenza kugqibelele, ngoko ungatyhafi ukuba kuthatha iinzame ezimbalwa ukufumana ukuxhoma kwenkqubo.Ngexesha kunye namava, uya kukwazi ukwenza ngempumelelo iisekethe zePCB ezintsonkothileyo nezisebenza kakhulu.
