Application
PCB hafu-gomba board inoreva kuchera kwechipiri uye chimiro muitiro mushure mekunge buri rekutanga raboorwa, uye pakupedzisira hafu yegomba resimbi inochengeterwa.Chinangwa ndechekushongedza zvakananga mupendero wegomba kumucheto mukuru kuchengetedza zvibatanidza uye nzvimbo, uye zvinowanzoonekwa mumasekete echiratidzo.
Half-gomba redunhu mabhodhi anowanzo shandiswa kukwirisa yakakwirira-density zvigadzirwa zvemagetsi, senge nharembozha, smart wachi, midziyo yekurapa, odhiyo nemavhidhiyo midziyo, etc. Vanogonesa yakakwirira redunhu density uye mamwe ekubatanidza sarudzo, kuita zvigadzirwa zvemagetsi zvidiki, zvireruke. uye inoshanda zvakanyanya.
Iyo isina-yakaputirwa hafu yegomba pamicheto yePCB ndechimwe chezvinhu zvinowanzo shandiswa mukugadzira PCB, uye basa rayo guru nderekugadzirisa PCB.Mukuita kwePCB board kugadzirwa, nekusiya hafu maburi pane dzimwe nzvimbo pamucheto wePCB board, iyo PCB board inogona kugadzikwa pane mudziyo kana imba ine screws.Panguva imwecheteyo, panguva yePCB board assembly process, iyo hafu gomba inobatsirawo kuisa uye kurongedza bhodhi rePCB kuve nechokwadi chechokwadi uye kugadzikana kwechigadzirwa chekupedzisira.
Iyo hafu yegomba yakaputirwa padivi redunhu bhodhi ndeyekuvandudza kuvimbika kwekubatana kwedivi rebhodhi.Kazhinji, mushure mekunge bhodhi redunhu rakadhindwa (PCB) rachekwa, iyo yakafumurwa yemhangura layer iri kumucheto inozoburitswa, iyo inowanzoitika kune oxidation uye corrosion.Kuti ugadzirise dambudziko iri, mhangura yemhangura inowanzoputirwa mumudziyo wekudzivirira ne electroplating kumucheto kwebhodhi muhafu yegomba kuti ivandudze iyo oxidation kuramba uye kusagadzikana kwemarara, uye inogonawo kuwedzera nzvimbo yewelding nekuvandudza kuvimbika kwe kubatana.
Muchigadziro chekugadzirisa, maitiro ekudzora chigadzirwa chemhando mushure mekugadzira maburi-metallized pamucheto webhodhi, seminzwa yemhangura pamadziro egomba, nezvimwewo, yakagara iri dambudziko rakaoma mukugadzirisa.Kune rudzi urwu rwebhodhi rine mutsara wose wemakomba semi-metallized The PCB board inoratidzwa neine dhayamita yegomba shoma, uye inonyanya kushandiswa kumwanasikana bhodhi rebhodhi reamai.Kuburikidza nemaburi aya, inosungirirwa pamwe chete nebhodhi raamai uye mapini ezvikamu.Paunenge uchitengesa, zvinotungamira kune isina kusimba soldering, yenhema soldering, uye yakakomba bhiriji pfupi pfupi pakati pemapini maviri.
FAQs
Zvinogona kubatsira kuisa maburi akaiswa (PTH) pamupendero webhodhi.Semuenzaniso kana iwe uchida kutengesa maviri maPCB pane mumwe nemumwe mu90 ° angle kana paunenge uchitengesa PCB kune simbi casing.
Semuenzaniso, musanganiswa weakaomesesa microcontroler modules ane akajairika, ega akagadzirwa maPCB.Mamwe maapplication anoratidzwa, HF kana ceramic modules anotengeswa kune base yakadhindwa redunhu bhodhi.
Kudhirowa- yakaputirwa negomba (PTH) - mapaneru plating - kutamisa mufananidzo - pateni plating -pth hafu gomba- mitsetse - etching - solder mask - silkscreen - kurapwa kwepamusoro.
1.Diameter ≥0.6MM;
2.Chinhambwe pakati pegomba mupendero ≥0.6MM;
3. Iyo yakafara ye etching mhete inoda 0.25mm;
Half-gole inzira yakakosha.Kuti ive nechokwadi chekuti mugomba mava nemhangura, inofanirwa kugaya mupendero isati yaisa nzira yemhangura.Iyo yakawanda hafu-gomba PCB idiki kwazvo, saka mutengo wayo unodhura kupfuura yakajairika PCB.
