Nekukurumidza kusimudzira kweindasitiri yePCB, PCB iri kufamba zvishoma nezvishoma yakananga kwainotungamira mitsetse yakatetepa, madiki madiki, uye yakakwirira mareshiyo (6: 1-10: 1). Iyo gomba mhangura inodiwa i20-25Um, uye DF mutsara wemutsara uri pasi pe4mil. Kazhinji, makambani ekugadzira PCB ane matambudziko ne electroplating firimu. Chikwata chemufirimu chinokonzeresa kutenderera kupfupi kwakananga, izvo zvinozokanganisa chiyero chegoho chebhodhi rePCB kuburikidza nekuongorora kweAOI. Yakakomba firimu clip kana mapoinzi akawandisa haagone kugadziriswa zvakananga kutungamirira kune zvimedu.

Nheyo yekuongorora yePCB sandwich firimu
① Ukobvu hwemhangura hwepateni plating wedunhu yakakura kupfuura ukobvu hwefirimu rakaoma, izvo zvinokonzeresa kusungirirwa kwefirimu. (Ukobvu hwefirimu rakaoma rinoshandiswa neiyo general PCB fekitori i1.4mil)
② Ukobvu hwemhangura uye tin yepateni plating wedunhu inodarika ukobvu hwefirimu rakaoma, izvo zvinogona kukonzera bhaisikopo kusungirirwa.

Ongororo yezvikonzero zvepinching
①Iyo pateni yekuisa density iripo yakakura, uye copper plating yakanyanyisa.
②Iko hakuna mutsara wemupendero kumigumo yese yebhazi rinobhururuka, uye nzvimbo yakakwirira iripo yakaputirwa nefirimu gobvu.
③Iyo AC adapta ine yakakura ikozvino kupfuura chaiyo yekugadzira bhodhi yakaiswa ikozvino.
④C/S side uye S/S side zvakadzoserwa kumashure.
⑤Muto wacho idiki kuti usaite bhodhi rinorovera firimu rine 2.5-3.5mil pitch.
⑥Kugovewa kwazvino hakuna kuenzana, uye silinda yemhangura yekuisa haina kuchenesa anode kwenguva yakareba.
⑦ Kupinza kwakashata ikozvino (isa iyo isiriyo modhi kana kuisa nzvimbo isiriyo yebhodhi)
⑧Iyo nguva yekudzivirira ikozvino yePCB board muhumburumbira yemhangura yakarebesa.
⑨Magadzirirwo emagadzirirwo epurojekiti haana musoro, uye iyo inoshanda electroplating nzvimbo yemifananidzo yakapihwa neprojekiti haina kururama.
⑩Mutsetse wemutsara wePCB bhodhi idiki zvakanyanya, uye iyo yedunhu dhizaini repamusoro-inonetsa bhodhi iri nyore kutora firimu.
