Application
Maitiro ekuputirwa hafu maburi ndeaya:
1. Gadzira gomba rehafu-parutivi nekaviri V-yakaita yekucheka chishandiso.
2. Chibooreso chechipiri chinowedzera maburi padivi pegomba, chinobvisa ganda remhangura pachine nguva, chinoderedza maburrs, uye chinoshandisa groove cutters pachinzvimbo chezvibooresa kuti chiwedzere kumhanya nekudonha.
3. Nyura mhangura ku electroplate substrate, kuitira kuti chidimbu chemhangura chigadzirwe pamadziro egomba regomba rakatenderera pamucheto webhodhi.
4. Kugadzirwa kweyekunze layer yedunhu mushure mekucheka, kuratidzwa, uye kukura kweiyo substrate mukutevedzana, iyo substrate inoiswa pasi pechipiri mhangura plating uye tin plating, kuitira kuti mhangura yemhangura pamadziro egomba regomba rakatenderera pamucheto we. bhodhi rakasvibiswa uye mhangura yemhangura yakafukidzwa yakafukidzwa netini yekudzivisa kuora;
5. Kuumba hafu-gomba cheka gomba rakatenderera pamucheto wepuranga muhafu kuti uite hafu-gomba;
6. Muchinhanho chekubvisa firimu, firimu re-anti-electroplating rakatsikirirwa panguva yekufambisa firimu inobviswa;
7. Etching substrate yakavharidzirwa, uye mhangura yakazaruka pamucheto wekunze we substrate inobviswa ne etching;
8. Tini inobvisa substrate inobviswa tini, kuitira kuti tini pamadziro ehafu-gomba inogona kubviswa, uye mhangura yemhangura pamadziro ehafu-gomba inoratidzwa.
9. Mushure mekugadzira, shandisa tepi tsvuku kuti unamatire mabhodhi eyuniti pamwe chete, uye bvisa maburrs kuburikidza nealkaline etching line.
10. Mushure mechipiri chemhangura yemhangura uye tin plating pa substrate, gomba rakatenderera pamucheto webhodhi rinochekwa nepakati kuita hafu yegomba, nokuti mhangura yemhangura yemadziro egomba yakafukidzwa netini, uye iyo mhangura yemhangura yegomba rusvingo yakanyatsopindirana nemhangura yemhangura yekunze kweiyo substrate Connection, inosanganisira yakasimba yekubatanidza simba, inogona kudzivirira zvinobudirira mhangura yemhangura pamadziro egomba kubva pakudhonzwa kana kuputika kwemhangura pakucheka;
11. Mushure mekunge hafu-gomba kuumbwa kwapera, firimu rinobviswa uye rozoiswa, kuitira kuti nzvimbo yemhangura irege kuva oxidized, zvinobudirira kudzivisa kuitika kwemhangura yakasara kana kunyange pfupi, uye kuvandudza chiyero chegoho chehafu yesimbi. -gomba PCB redunhu bhodhi.
FAQs
Yakaputirwa hafu-gomba kana castellated-gomba, idanho rakaita chitambi mupendero kuburikidza nekucheka nepakati pane iyo rondedzero.Yakaputirwa hafu-gomba ndeyepamusoro-soro yemapendero akapfava emapuranga edunhu akadhindwa, anowanzo shandiswa kubatanidza bhodhi-kune-bhodhi.
Via inoshandiswa seyakabatana pakati pemhangura zvidimbu paPCB nepo PTH ichiwanzoitwa yakakura kupfuura vias uye inoshandiswa segomba rakavharwa rekugamuchirwa kwechikamu chinotungamira - senge asiri SMT resistors, capacitors, uye DIP package IC.PTH inogona zvakare kushandiswa semaburi ekubatanidza mechaniki nepo vias ingasadaro.
Iyo yekuputira pamaburi imhangura, conductor, saka inobvumira conductivity yemagetsi kufamba nemubhodhi.Zvisina-plated kuburikidza nemakomba hazvina conductivity, saka kana iwe ukazvishandisa, iwe unogona chete kuva nemakwara emhangura anobatsira kune rumwe rutivi rwebhodhi.
Kune mhando nhatu dzemakomba muPCB, Yakaputirwa Neburi (PTH), Non-Plated Through Hole (NPTH) uye Via Holes, izvi hazvifanirwe kuvhiringika neSlots kana Cut-outs.
