Best Technology yenye abavelisi pcb ilungileyo eprintiweyo ababoneleli ngebhodi yesekethe e China
Kummandla omkhulu wobunjineli kunye nemveliso, kukho ilizwe elifihliweyo lemingxuma, ngalinye linenjongo yalo eyahlukileyo kunye nesikhundla. Le mingxuma idlala indima ebalulekileyo ekuququzeleleni imisebenzi eyahlukeneyo kwiinkqubo zoomatshini nezombane. Kule bhlog, siza kuqalisa uhambo lokujonga iintlobo ezahlukeneyo zemingxuma kwibhodi yesekethe eprintiweyo. Ke, bhinqa amabhanti ezihlalo kwaye masingene kwihlabathi elinomdla kwezi zinto zibalulekileyo zobunjineli.
Iintlobo eziqhelekileyo zemingxuma kwi-PCB
Emva kokuphonononga ibhodi yesekethe, umntu uya kufumana uluhlu lwemingxuma esebenzela iinjongo ezithile. Ezi ziquka imingxunya ye-Via, i-PTH, i-NPTH, imingxuma eyimfama, imingxuma efihliweyo, imingxuma ye-Counterbore, imingxuma ye-Countersunk, imingxuma yendawo, kunye nemingxuma ye-Fiducial. Uhlobo lomngxuma ngamnye luzalisekisa indima ekhethekileyo kunye nomsebenzi ngaphakathi kwePCB, iyenza ukuba kubaluleke kakhulu ukuziqhelanisa neempawu zabo ukuququzelela uyilo lwePCB olululo.
1. Ngemingxuma
Ngemingxuma yimingxuma emincinci edibanisa iileya ezahlukeneyo zebhodi yesekethe eprintiweyo (PCB). Baququzelela ukuhamba okungenamthungo kwemiqondiso kunye namandla phakathi kweengqimba, okwenza ukuba uyilo olusebenzayo lwesekethe kunye nokuhanjiswa. I-Vias ingahlelwa kwiintlobo ezimbini: I-Plated Through-Holes (PTH) kunye ne-Non-Plated Through-Holes (NPTH), nganye ikhonza imisebenzi eyahlukeneyo.
2. PTH (Icandelwe ngomngxuma)
I-Plated Through-Holes (PTH) zi-vias kunye ne-conductive material coating iindonga zangaphakathi. Ii-PTHs ziseka uqhagamshelo lombane phakathi kweeleya ezahlukeneyo ze-PCB, ezivumela ukuhamba kwemiqondiso kunye namandla. Badlala indima ebalulekileyo kumacandelo okudibanisa, ukuququzelela ukuhamba kombane, kunye nokuqinisekisa ukusebenza kwesekethe.
3. I-NPTH (Engatyalwanga ngomngxuma)
I-Non-Plated Through-Holes (NPTH) ayinayo i-coative coating kwiindonga zabo zangaphakathi, okwenza ukuba zilungele iinjongo zoomatshini kuphela. Le mingxuma isetyenziselwa ukuxhasa oomatshini, ukulungelelaniswa, okanye njengezikhokelo zokubeka, ngaphandle kokuseka naluphi na uxhulumaniso lombane. Ii-NPTH zibonelela ngokuzinza kunye nokuchaneka, ziqinisekisa ukulungelelaniswa okufanelekileyo kwamacandelo ngaphakathi kwebhodi yesekethe. Eyona nto ihluke kakhulu phakathi kwe-PTH kunye ne-NPTH yi-foil yobhedu iya kufakwa eludongeni lomngxuma ngelixa i-NPTH kungekho mfuneko yokwenza ipleyiti.
4. Imingxunya eyimfama
Imingxunya engaboniyo yimingxuma egrunjiweyo engena icala elinye kuphela lebhodi yesekethe. Ngokuyintloko baqeshwe ukudibanisa umaleko wangaphandle webhodi kunye nomgangatho wangaphakathi, okwenza ukuba icandelo lixhonywe kwelinye icala ngelixa lihlala lifihliwe kwelinye. Imingxuma eyimfama ibonelela ngezinto ezahlukeneyo kwaye inceda ukwandisa indawo kuyilo lwebhodi yesekethe enzima.
5. Imingxunya eGqwebileyo
Imingxuma engcwatywayo ivalwe ngokupheleleyo ngaphakathi kwebhodi yesekethe, idibanisa iileyile zangaphakathi ngaphandle kokwandisa kwimigangatho yangaphandle. Le mingxunya ifihliwe kumacala omabini ebhodi kwaye isebenze ukuseka imidibaniso kunye neendlela phakathi kwemigangatho yangaphakathi. Imingxuma engcwatyiweyo ivumela uyilo lwebhodi yesekethe exineneyo, ukunciphisa ukuntsonkotha komzila wendlela kunye nokuphucula ukusebenza ngokubanzi kwebhodi. Banikezela ngesisombululo esingenamthungo kunye nesicwebileyo ngaphandle kokuvezwa komphezulu.
6. Imingxunya ye-Counterbore
Imingxunya ye-Counterbore yi-cylindrical recesses eyenzelwe ukuhlalisa iintloko zee-bolts, ii-nuts, okanye izikrufu. Banikezela ngomgodi osezantsi osicaba ovumela ukuba izibophelelo zihlale zigungxulwe okanye zingaphantsi kancinci kumphezulu wezinto. Umsebenzi ophambili wemingxuma echasene ne-counterbore kukuphucula ubuhle kunye nokusebenza koyilo ngokubonelela ngenkangeleko egudileyo kwaye elinganayo. Le mingxunya iqhele ukufunyanwa kwi-woodworking, isinyithi, kunye nezicelo zobunjineli apho indawo efihliweyo okanye enkulu yokuthwala ifunwa.
7. Imingxunya yee-Countersunk
Imingxunya ye-countersunk ziindawo zokulala eziyilwe ukubeka iintloko ezineengile zezikrufu okanye iziqhoboshi. Baqeshelwe ukuqinisekisa ukuba iintloko ze-screw zilala zigungxulwa okanye zingaphantsi kancinane kumphezulu wezinto eziphathekayo. Imingxunya ye-Countersunk isebenza zombini iinjongo zobuhle kunye nokusebenza, ukubonelela ngokugqibeleleyo kunye nokuphela kwesiphako ngelixa unciphisa umngcipheko wee-snags okanye iiprotrusions. Ukuguquguquka kwazo kuzenza zilungele usetyenziso olwahlukeneyo, ukusuka kwimveliso yefenitshala ukuya kubunjineli be-aerospace.
8. Indawo Imingxunya
Imingxunya yeNdawo, ekwabizwa ngokuba yiMingxunya yeReferensi okanye iMingxunya yeZixhobo, isebenza njengeendawo eziphambili zesalathiso zokulungelelaniswa nokubeka amacandelo, iinxalenye, okanye izilungiso ngexesha lenkqubo yokuvelisa okanye yokuhlanganisa. Le mingxuma ibekwe ngokucwangcisekileyo kuyilo lokuqinisekisa ulungelelwaniso oluchanekileyo kunye noluhambelanayo, ukwenza ukudibanisa okusebenzayo kunye nokunciphisa iimpazamo.
9. Imingxuma eyiFiducial
Imingxunya yeFiducial, ekwabizwa ngokuba yiFiducial Marks okanye i-Alignment Marks, yimingxuma emincinci echanekileyo okanye iimpawu ezibekwe phezu komhlaba okanye i-PCB (iBhodi yeSekethe eShicileleyo). Le mingxunya isebenza njengeendawo zokujonga imbonakalo yeenkqubo zombono, iinkqubo ezizenzekelayo, okanye iikhamera zokujonga umatshini.
Njengoko sigqiba uhambo lwethu kwihlabathi elinomdla lemingxuma kubunjineli, siye safumana ukuqonda okunzulu kwemisebenzi kunye nezikhundla zemigodi ye-counterbore, imingxuma edibeneyo, ngemingxuma, i-PTH, i-NPTH, imingxuma eyimfama, kunye nemingxuma efihliweyo. Le mingxunya zizinto ezibalulekileyo kumashishini ahlukeneyo, igalelo kubuhle, ukusebenza, kunye nokusebenza kakuhle koyilo.
Emva kokwazisa ngamnye kubo, bekufanele ukuba uzuze ukuqonda okunzulu kwemisebenzi yabo, ndiyathemba ukuba oku kuluncedo kuwe imingxunya yoyilo kwiprojekthi yakho yePCB!!
