Kuba PCB indlwane, iinjineli baqhelene nemithetho esisiseko, ezifana nesting izithuba okanye non-spaced, usebenzisa V-CUT okanye imingxunya isitampu ukudityaniswa, ukongeza imiphetho inkqubo, imingxuma yokubeka, kwaye amanqaku amanqaku. Nangona kunjalo, i-PCB iza kwiimilo ezahlukeneyo, kwaye ukulandela le migaqo isisiseko akwanelanga. Kubalulekile ukuqonda inkqubo yemveliso ngokweenkcukacha zokuqinisekisa ukufukama ngokufanelekileyo, okuya kunceda ukuphepha imiba enokwenza i-PCB ingabinamveliso okanye ibangele inkunkuma yemveliso. Le mizekelo ilandelayo ibalaselisa iimeko ezahlukeneyo zokuzalela iimilo zePCB ngeenjongo zemfundo.
CNC + V-CUT Nesting
Ukusebenzisa i-Milling + V-CUT Indlela yokuNesting:
Kule meko, indlwane yenziwa ngaphandle kokubeka izithuba phezulu, ezantsi, ekhohlo nasekunene. Ukuba imilo yangaphandle ye-PCB inenotshi ezingaqhelekanga, ukufukama okungahlukaniyo kuyaba nzima. Oku kungenxa yokuba iinotshi ezincinci, ezincinci kuneradiyasi yesixhobo sokungqusha, azinakusilwa ngokufanelekileyo, kwaye iibhutsi zinokuvela emva kokusila. Ukunqanda oku, shiya isithuba se-2mm phezulu nasezantsi, kwaye uqinisekise ukuba akukho V-CUT ibekwe apho kukho iinotshi. Ngale ndlela, isixhobo sokugaya sinokunqanda ukwenza ii-burrs, njengoko kubonisiwe kwimifanekiso.
L-I-PCB enemilo yokuzalela:
Kwii-PCB ezimile okwe-L, kusetyenziswa indlela yokuzalela umva ukugcina imathiriyeli. Nangona kunjalo, xa iilayini ze-V-CUT zingahambelani ngokuthe tye, kuba nzima ukusebenzisa i-V-CUT yokubunjwa. Ukuba i-V-CUT iyatsitywa, iindleko ziya kunyuka kakhulu. Isisombululo apha kukushiya isithuba se-2mm kwimida yasekhohlo nasekunene ukuqinisekisa ukumila ngendlela eyi-V-CUT, njengoko kubonisiwe kumzobo.

Ukususa iiBurrs kuMda wePCB
I-V-CUT i-Bridging Method yokuzalela:
Xa usebenzisa i-V-CUT ibhuloho yokuzalela, ukuba imigca yemilo yangaphandle ayihambelani, iikona ezibukhali zingenzeka, kwaye isixhobo sokugaya asikwazi ukufikelela kwezo ndawo. Isisombululo esiqhelekileyo kukongeza imingxuma yokugaya iikona ezibukhali. Nangona kunjalo, le ndlela ayifanelekanga, njengoko inokushiya ii-burrs ezininzi. Endaweni yoko, eyona ndlela isebenzayo kukusebenzisa ibhulorho ye-V-CUT ukwenza indlwane, kunye nemiphetho yenkqubo eyongeziweyo. Ngale ndlela, neekona ezincinci ezibukhali zinokugutywa ngokufanelekileyo ngaphandle kokushiya i-burrs.
I-PCB emise ngendlela engaqhelekanga:
I-PCB enemilo engaqhelekanga ayinakuxhonywa kusetyenziswa i-V-CUT, njengoko ukwenza oko kuya kubangela iikona ezibukhali apho isixhobo sokusila singenakufikelela khona, sishiya ii-burrs. Kwiimilo ezinjalo ezingaqhelekanga, indlela yokudibanisa umngxuma wesitampu kufuneka isetyenziswe.
Iindlela zokuzalela iBhodi yeHalf-Hole
Indawo enesiqingatha somngxuma:
Kwiibhodi ezinesiqingatha somngxuma, i-V-CUT ayinakusetyenziswa ngenxa yokuba iya kunqumla ubhedu kwimingxuma enesiqingatha, ibenze bangasebenzi ngombane. Endaweni yoko, ukucubungula okukhethekileyo kufuneka kusetyenziswe kwezi zikhundla ze-half-hole, ukuqinisekisa ukuba kukho imvume eyaneleyo yesixhobo sokugaya ukuphepha ukulimaza ubhedu, njengoko kuboniswe kumfanekiso.
Iibhodi ezineHalf-Hole ezinoQhagamshelwano lwangaphandle:
Xa ufuye iibhodi ezinesiqingatha somngxuma, ngakumbi xa imingxunya enesiqingatha ibekwe emacaleni, kubalulekile ukushiya isithuba kwisixhobo sokusila. Indlela yokuzalela umva iyacetyiswa kwiibhodi ezinesiqingatha somngxuma omacala amathathu. Le ndlela ibeka imimandla efunekayo yokugaya kunye, ishiya iindawo ngaphandle kokugaya ngaphandle ukuze kube lula ukudibanisa. Njengoko kubonisiwe kulo mzobo, ukuzalela ngaphandle kwezithuba kuya kwenza ibhodi ingashukumi.
Iibhodi ezinesiqingatha somngxuma omacala amane:
Kwiibhodi ezinesiqingatha ezinesiqingatha somngxuma, kubalulekile ukushiya imvume eyaneleyo yokugaya. Iikona kufuneka zidibaniswe ngokusebenzisa imingxuma yesitampu ukuphepha ukuphuka kwebhodi ngenxa yeendawo ezincinci zokuxhuma. Ukuba indawo yokudibanisa incinci kakhulu, unokucinga ukuba ungasebenzisi imingxuma yesitampu kwaye udibanise ngokuthe ngqo iikona zebhodi.
Ukuthathela ingqalelo amaCandelo kuMda weBhodi
Amacandelo oMda:
Ukuba amacandelo adlulela ngaphaya kwemida ye-PCB, i-non-spaced nesting ayifanele isetyenziswe, njengoko amacandelo aya kuphazamisana nabanye xa efulelwe. Xa uqulunqa iibhodi ezinamacandelo adlulela ngaphaya komda, imida yenkqubo kufuneka yongezwe kunye ne-cutouts ukuvumela amacandelo ukuba abekwe kwaye athengiswa ngokuchanekileyo.
Amacandelo Angaphaya koMda weBhodi:
Xa iibhodi zendlwane ezinamacandelo angaphezulu komphetho, indlela yokubuyela umva yokuzalela kufuneka isetyenziswe, kunye nezixhobo ezandisiweyo zijonge ngaphandle. Oku kuqinisekisa ukuba indibano inokwenzeka ngaphandle kokuphazamiseka. Ukuba amacandelo ajongene nangaphakathi, aya kungqubana kunye namacandelo kwezinye iibhodi, ukukhusela ukudibanisa, njengoko kuboniswe kwimifanekiso.
Isitampu soMngxuma wokuvala iNesting
I-PCB engaqhelekanga kunye neMilo engqukuva:
- Iibhodi ezimile ngendlela engaqhelekanga okanye ezingqukuva kufuneka zisebenzise ibhulorho yomngxuma wesitampu ukwenzela ukuzalela, njengoko i-V-CUT ayinakusetyenziswa kwezo milo. Kwiibhodi ezijikelezileyo, i-V-CUT i-non-spaced nesting ingakhokelela kwiindawo ezincinci zokudibanisa, ezinokubangela ukuba ibhodi iphule lula. Emva kwemveliso, imiphetho inokuba ne-burrs. Xa usebenzisa uqhagamshelo lwemingxuma yesitampu, kubalulekile ukuqinisekisa ukubekwa okufanelekileyo kunye nezithuba ezifanelekileyo zemingxuma yesitampu. Ukuba imingxuma ibekwe kude kakhulu, ibhodi inokuphuka, kwaye ukuba imingxuma isondele kakhulu, ukudibanisa kunokungonelanga kwaye kubangele ukuphuka.
Umngxuma wesitampu + V-CUT
Ukudityaniswa kwe-V-CUT kunye neSitampu seHole Nesting:
- Kwiibhodi ezinemilo yangaphandle engaqhelekanga, indibaniselwano ye-V-CUT kunye noqhagamshelo lomngxuma wesitampu ingasetyenziselwa ukuzalela. Nangona kunjalo, iindawo zokugaya ezigqithisileyo zinokubangela ukuba ibhodi iphuke. Ukuthintela oku, imingxuma yesitampu kufuneka yongezwe kwiindawo zokudibanisa ukubonelela ngenkxaso eyongezelelweyo kwaye ugweme ukuphulwa kwebhodi.
