Ndezvipi zvikonzero zvekubatanidzwa kwerosin muSMT chip processing?

I. Rosin joint inokonzerwa nemaitiro ekugadzirisa
1. Kushaikwa solder paste
2. Kusakwana kwehuwandu hwe solder paste inoshandiswa
3. Stencil, kuchembera, kudonha kwakashata
II.Rosin joint inokonzerwa nePCB zvinhu
1. PCB Mapedhi ane oxidized uye ane urombo solderability

btwe

2. Via maburi pamapedhi
III.Rosin joint inokonzerwa nechikamu zvinhu
1. Deformation yezvikamu zvepini
2. Oxidation yezvikamu zvepini
IV.Rosin joint inokonzerwa nemidziyo zvinhu
1. Iyo inokwirisa inofamba nekukurumidza muPCB kutapurirana uye chinzvimbo, uye kutama kwezvinorema zvinokonzeresa kunokonzerwa ne inertia huru.
2. Iyo SPI solder paste detector neAOI yekuongorora midziyo haina kuona inechekuita yekuputira solder paste nematambudziko ekuisa nenguva.
V. Rosin joint inokonzerwa nekugadzira zvinhu
1. Ukuru hwepadhi uye pini yechikamu hachifananidzi
2. Rosin joint inokonzerwa nemaburi ane simbi pane padhi
VI.Rosin joint inokonzerwa neanoshanda zvinhu
1. Kushanda kusina kujairika panguva yePCB kubika uye kutamisa kunokonzera PCB deformation
2. Kushanda zvisiri pamutemo mugungano uye kutamiswa kwezvinhu zvakapedzwa
Chaizvoizvo, izvi ndizvo zvikonzero zvemajoini erosin mune zvakapedzwa zvigadzirwa muPCB kugadzirisa kweSMT chigamba vanogadzira.Manongedzo akasiyana achave neakasiyana mikana yemajoini e rosin.Zvinotovapo chete mudzidziso, uye kazhinji hazviratidzike mukuita.Kana pane chimwe chinhu chisina kukwana kana chisina kunaka, tapota titumire e-mail.
