PCB kukanganisa idambudziko rakajairika muPCBA batch kugadzirwa, izvo zvinounza simba rakakura kuungano uye kuyedzwa.Nzira yekudzivirira sei dambudziko iri, tapota ona pasi apa.
Zvikonzero zvePCB kukanganisa ndezvizvi:
1. Kusarudzwa kwakashata kwePCB mbishi zvinhu, zvakadai sepasi T yePCB, kunyanya mapepa-based PCB, ane tembiricha yekugadzira yakanyanya, PCB inogonja.
2. Zvisizvo PCB dhizaini, kugoverwa kusina kuenzana kwezvikamu kuchaita kuti kuwedzere kupisa kwekunetseka kwePCB, uye zvibatanidza uye zvigadziko zvine maumbirwo makuru zvichakanganisawo PCB kuwedzera uye kuputika, zvichikonzera kukanganisa zvachose.
3. PCB dhizaini matambudziko, akadai maviri-mativi PCB, kana foil yemhangura kune rimwe divi yakakura zvakanyanya, senge waya yepasi, uye foil yemhangura kune rumwe rutivi idiki kwazvo, zvinokonzeresa kusaenzana shrinkage uye deformation pa. mativi ose.
4. Kusashandiswa kwakashata kwechigadziriso kana chinhambwe chekugadzirisa idiki zvakanyanya, sengewave soldering muchinachigunwe clamping chakanyanya kusimba, PCB ichawedzera uye deformation nekuda kwekupisa tembiricha.
5. Kupisa kwakanyanya mukatireflow ovenwelding inokonzeresa kukanganisa kwePCB.
Nekuda kwezvikonzero zviri pamusoro apa, mhinduro dzinotevera:
1. Kana mutengo nenzvimbo zvichibvumira, sarudza PCB ine Tg yakakwirira kana kuwedzera PCB ukobvu kuti uwane yakanakisa chikamu reshiyo.
2. Gadzira PCB zvinonzwisisika, nzvimbo yesimbi yemativi maviri inofanira kuva yakaenzana, uye mhangura yemhangura inofanira kuvharwa pasina dunhu, uye kuonekwa nenzira yegridhi kuti iwedzere kuoma kwePCB.
3. PCB inofanobikwa kareSMT muchinapa125℃/4h.
4. Rongedza gadziriso kana clamping chinhambwe kuti uve nechokwadi chekuti nzvimbo yePCB yekudziya yekuwedzera.
5. Welding process tembiricha yakaderera sezvinobvira, kunyorova kukanganisa kwaonekwa, kunogona kuiswa munzvimbo yekumisikidza, tembiricha reset, kusunungura kushushikana, kazhinji zvinogutsa mhedzisiro ichawanikwa.
