Graphitization ne electroplating pamakomba kana nemaburi pamucheto wePCB. Cheka mupendero webhodhi kuti uite mutsara wemakomba ehafu. Ma half holes aya ndiwo atinoti stamp hole pads.
1. Kuipa kwemaburi echitambi
①: Mushure mekunge bhodhi raparadzaniswa, rine chimiro chakafanana nesaha. Vamwe vanhu vanoti chimiro chembwa-zino. Zviri nyore kupinda mugoko uye dzimwe nguva inoda kutemwa nechigero. Nokudaro, mukugadzira nzira, nzvimbo inofanira kuchengetwa, uye bhodhi rinowanzoderedzwa.
②: Wedzera mutengo. Iyo yakaderera chitambi gomba ndeye 1.0MM gomba, saka iyi 1MM saizi inoverengerwa mubhodhi.
2. Basa remakomba echitambi akajairika
Kazhinji, iyo PCB ndeye V-CUT. Kana ukasangana nebhodhi rakakosha kana rakatenderedza, zvinokwanisika kushandisa gomba rechitambi. Bhodhi nebhodhi (kana bhodhi risina chinhu) zvakabatanidzwa nemakomba echitambi, ayo anonyanya kuita basa rekutsigira, uye bhodhi haizopararirwi. Kana iyo mold ikavhurwa, mold haipunzi. . Kazhinji kazhinji, dzinoshandiswa kugadzira PCB stand-alone modules, dzakadai seWi-Fi, Bluetooth, kana core board modules, dzinobva dzashandiswa sezvikamu zvekumira-oga kuti zviiswe pane imwe bhodhi panguva yegungano rePCB.
3. General spacing yemakomba zvitambi
0.55mm ~ 3.0mm (zvichienderana nemamiriro ezvinhu, inowanzoshandiswa 1.0mm, 1.27mm)
Ndedzipi mhando huru dzemakomba ezvitambi?
- Half gomba
- Gomba diki rine hafu hol
- Maburi atange kumucheto kwebhodhi
4. Zvidimbu zvegomba zvinodiwa
Zvichienderana nezvinodiwa uye kupedzisa kushandiswa kwebhodhi, kune mamwe maitiro ekugadzira anoda kusangana. Eg:
① Saizi: Inokurudzirwa kushandisa hukuru hunobvira saizi.
②Kurapwa kwepamusoro: Zvinoenderana nekuguma kwekushandiswa kwebhodhi, asi ENIG inokurudzirwa.
③ OL pad dhizaini: Inokurudzirwa kushandisa yakakura kwazvo OL padhi kumusoro uye pasi.
④ Nhamba yemakomba: Zvinoenderana nedhizaini; zvisinei, zvinozivikanwa kuti diki nhamba makomba, zvikuru kuoma PCB gungano muitiro.
Plated hafu-maburi anowanikwa pane ese akajairwa uye epamberi maPCB. Kune akajairwa PCB dhizaini, iyo shoma dhayamita yegomba rakaita c i1.2 mm. Kana uchida maburi madiki akaita se-c, nhambwe shoma pakati pemaburi maviri akavharwa hafu i0.55 mm.
Stamp Hole Manufacturing process:
Kutanga, ita iyo yose yakaputirwa kuburikidza negomba semazuva ose pamucheto webhodhi. Zvadaro shandisa chigayo chekucheka gomba nepakati pamwe chete nemhangura. Sezvo mhangura yakanyanya kuoma kukuya uye ichigona kuita kuti chibooreso chityoke, shandisa chibooreso chinorema chinorema nekumhanya kwepamusoro. Izvi zvinoita kuti pave nenzvimbo yakapfava. Imwe neimwe hafu-gomba inozoongororwa muchiteshi chakatsaurirwa uye inobviswa kana zvichidikanwa. Izvi zvinogadzira gomba rechitambi ratinoda.
