Best Technology ndeimwe yakanakisisa pcb vagadziri uye akadhindwa redunhu bhodhi vatengesi mu China
Munzvimbo yakakura yeinjiniya nekugadzira, kune nyika yakavanzika yemakomba, imwe neimwe iine chinangwa chayo chakasiyana uye chinzvimbo. Aya maburi anoita basa rakakosha mukufambisa mabasa akasiyana mukati memakanika uye emagetsi masisitimu. Mubhuku rino, tichatanga rwendo rwekuongorora mhando dzakasiyana dzemaburi mubhodhi redunhu rakadhindwa. Saka, sunga mabhandi ako uye ngatitarise munyika inonakidza yeaya akakosha einjiniya maficha.
Mhando Dzakajairika Makomba muPCB
Paunenge uchiongorora bhodhi redunhu, mumwe anowana ruzhinji rwemakomba anoshanda zvakanangana nechinangwa. Izvi zvinosanganisira Via makomba, PTH, NPTH, Mapofu makomba, Akavigwa makomba, Counterbore makomba, Countersunk makomba, Nzvimbo maburi, uye Fiducial makomba. Mhando yega yega gomba inozadzisa basa rakasiyana uye basa mukati mePCB, zvichiita kuti zvive zvakakosha kuti uzvizive nehunhu hwavo kuti ufambise yakakwana PCB dhizaini.
1. Via Makomba
Via maburi maburi madiki anobatanidza akaturikidzana akasiyana edhinda redunhu board (PCB). Ivo vanofambisa kuyerera kusina musono kwezviratidzo uye simba pakati pematanho, zvichigonesa dhizaini dhizaini uye kutapurirana. Vias inogona kuiswa mumhando mbiri: Plated Through-Holes (PTH) uye Non-Plated Through-Holes (NPTH), imwe neimwe ichishanda akasiyana mabasa.
2. PTH (Yakanyikwa neburi)
Plated Through-Holes (PTH) ari vias ane conductive zvinhu coating mukati madziro. PTHs inomisikidza kubatanidza kwemagetsi pakati pezvikamu zvakasiyana zvePCB, zvichibvumira kupfuura kwezviratidzo uye simba. Ivo vanoita basa rakakosha mukubatanidza zvikamu, kufambisa kuyerera kwemagetsi ikozvino, uye kuve nechokwadi chekushanda kwedunhu.
3. NPTH (Isina-Plated through-Hole)
Non-Plated Through-Holes (NPTH) inoshaya iyo conductive coating pamadziro emukati, zvichiita kuti ive yakakodzera kune zvemuchina chete. Aya maburi anoshandiswa kutsigira mechanika, kurongeka, kana semadhiraivha ekuisa, pasina kumisikidza chero magetsi ekubatanidza. NPTHs inopa kugadzikana uye kurongeka, kuve nechokwadi kurongeka kwakaringana kwezvikamu mukati mebhodhi redunhu. Iyo inonyanya kusiyanisa pakati pePTH neNPTH ndeye foil yemhangura ichaputirwa mugomba madziro nepo NPTH isingade kuita ndiro.
4. Makomba Mapofu
Mabofu maburi maburi akaboorwa zvishoma anopinda divi rimwe chete redunhu. Vanonyanya kushandiswa kubatanidza kunze kwebhodhi nemukati, zvichiita kuti chikamu chikwiridzwe kune rumwe rutivi chinoramba chakavigwa kubva kune rimwe. Mabofu maburi anopa kuita kwakasiyana-siyana uye anobatsira kuwedzera nzvimbo mumadhizaini akaoma edunhu redunhu.
5. Makomba Akavigwa
Makomba akavigwa akavharirwa zvachose mukati mebhodhi redunhu, achibatanidza zvidimbu zvemukati pasina kuenderera kune kunze. Maburi aya akavanzwa kubva kumativi ese ebhodhi uye anoshanda kumisikidza kubatanidza uye nzira pakati pemukati memukati. Makomba akavigwa anobvumira denser redunhu dhizaini dhizaini, kudzikisa kuomarara kwenzira dzenzira uye kuwedzera kushanda kwese kwebhodhi. Ivo vanopa isina musono uye compact mhinduro pasina chero kuratidzwa kwepamusoro.
6. Counterbore Holes
Counterbore maburi ma cylindrical recesses akagadzirwa kuti agare misoro yemabhaudhi, nzungu, kana screws. Ivo vanopa yakadzika-yakadzika mhango iyo inobvumira iyo fasteners kuti igare yakapfava kana zvishoma pazasi pepamusoro pechinhu. Basa rekutanga remaburi e counterbore ndere kusimudzira aesthetics uye mashandiro edhizaini nekupa yakatsetseka uye kunyange kutaridzika. Aya maburi anowanzo kuwanikwa mukugadzira huni, simbi, uye engineering application apo yakavanzika kana yakakura inotakura nzvimbo inodiwa.
7. Countersunk Holes
Countersunk maburi marecese akagadzirirwa kuisa misoro ine makona yemasiruuru kana zvisungo. Ivo vanoshandirwa kuve nechokwadi chekuti screw misoro inorara yakapfava kana zvishoma pazasi pezvinhu. Countersunk maburi anoshanda ese anoyevedza uye anoshanda zvinangwa, achipa yakapfava uye isina kukanganisa kupedzisa uku ichideredza njodzi ye snags kana protrusions. Kuita kwavo kwakasiyana-siyana kunoita kuti vakwanise kushandiswa kwakasiyana-siyana, kubva pakugadzira fenicha kuenda kuaerospace engineering.
8. Nzvimbo Makomba
Nzvimbo Holes, inozivikanwawo seReference Holes kana Tooling Holes, inoshanda seyakakosha mapoinzi ekumisikidza nekumisikidza zvikamu, zvikamu, kana zvigadziriso panguva yekugadzira kana magungano maitiro. Aya maburi akaiswa zvine hungwaru mudhizaini kuti ave nechokwadi chekurongeka uye kuenderana, kugonesa kuungana kwakanaka uye kuderedza kukanganisa.
9. Fiducial Makomba
Fiducial Holes, anonziwo Fiducial Marks kana Alignment Marks, maburi madiki chaiwo kana mamaki akaiswa pamusoro kana PCB (Yakadhindwa Circuit Board). Aya maburi anoshanda seanoona mareferensi mapoinzi ekuona masisitimu, otomatiki maitiro, kana muchina ekuona makamera.
Sezvatinopedzisa rwendo rwedu kuburikidza nenyika inonakidza yemakomba muinjiniya, takawana kunzwisisa kwakadzama kwemabasa uye zvinzvimbo zvemakomba e-counterbore, makomba akanyura, kuburikidza nemakomba, PTH, NPTH, maburi mapofu, uye makomba akavigwa. Aya maburi zvinhu zvakakosha mumaindasitiri akasiyana, zvichibatsira kune aesthetics, kushanda, uye kugona kwezvigadziriso.
Mushure mekusuma mumwe nemumwe wavo, iwe unofanirwa kunge wawana kunzwisisa kwakadzama kwemabasa avo, vimba izvi zvinobatsira kwauri maburi ekugadzira paPCB chirongwa chako !!
