1.Design for Manufacturability yePCBA
Iyo manufacturability dhizaini yePCBA inonyanya kugadzirisa dambudziko rekusangana, uye chinangwa ndechekuwana yakapfupika maitiro nzira, yepamusoro solder pass rate, uye yakaderera mutengo wekugadzira.Iyo dhizaini yemukati inonyanya kusanganisira: dhizaini nzira, dhizaini dhizaini pamusangano wepamusoro, padhi uye solder mask dhizaini (inoenderana nekupfuura-kuburikidza mwero), dhizaini yekupisa, dhizaini yekuvimbika kwegungano, nezvimwe.
(1)PCBA Manufacturability
Iyo manufacturability dhizaini yePCB inotarisa pa "manufacturability", uye zvinyorwa zvekugadzira zvinosanganisira kusarudzwa kweplate, press-fit structure, annular ring design, solder mask design, surface treatment uye panel design, nezvimwewo iye PCB.Yakaganhurirwa nemaitiro ekugadzirisa uye kugona, iyo yakaderera mutsara upamhi uye mutsara mutsara, shoma gomba dhayamita, shoma pad mhete mhete, uye shoma solder mask gap inofanirwa kuenderana nePCB kugadzirisa kugona.Iyo yakagadzirirwa stack Iyo layer uye lamination chimiro chinofanira kuenderana nePCB yekugadzirisa tekinoroji.Naizvozvo, iyo manufacturability dhizaini yePCB inotarisana nekusangana nekuita kugona kwePCB fekitori, uye kunzwisisa nzira yekugadzira PCB, kuyerera kwemaitiro uye kugona kwekuita ndiyo hwaro hwekuita dhizaini.
(2) Kubatanidzwa kwePCBA
Iyo PCBA's assemblability dhizaini inotarisa pa "assemblability", ndiko kuti, kumisikidza yakagadzikana uye yakasimba processability, uye kuwana yepamusoro-mhando, yepamusoro-inoshanda uye yakaderera-mutengo soldering.Zviri mukati mekugadzira zvinosanganisira kusarudzwa kwepakiti, dhizaini yedhizaini, nzira yekugadzira (kana nzira yekugadzira nzira), dhizaini yechikamu, simbi mesh dhizaini, nezvimwe. Izvi zvese zvinodiwa zvekugadzira zvinoenderana nepamusoro welding goho, kukwirira kwekugadzira kwekugadzira, uye kuderera kwemutengo wekugadzira.
2.Laser soldering process
Laser solder tekinoroji ndeyekuvhenekesa iyo pad nzvimbo ine yakanyatso kutariswa laser beam nzvimbo.Mushure mekutora simba relaser, nzvimbo inotengeswa inopisa nekukurumidza kunyungudutsa solder, uye inomisa laser irradiation kuti itonhodze nzvimbo inotengeswa uye kuomesa solder kuti iite solder joint.Nzvimbo yewelding inodziiswa munharaunda, uye mamwe mativi egungano rose haatombokanganiswa nekupisa.Iyo laser irradiation nguva panguva yewelding inowanzongoita mazana mashoma milliseconds.Kusina-kusangana soldering, hapana mechanical stress pane pad, yakakwirira nzvimbo kushandiswa.
Laser welding yakakodzera yekusarudza reflow soldering process kana majoini achishandisa tin waya.Kana chiri chikamu cheSMD, unofanirwa kuisa solder paste kutanga, wozotengesa.Iyo solder process yakakamurwa kuita nhanho mbiri: yekutanga, solder paste inoda kupisa, uye majoini e solder anotangwa zvakare.Mushure maizvozvi, iyo solder paste inoshandiswa pakutengesa inonyungudutswa zvachose, uye solder inonyorovesa zvachose padhi, pakupedzisira ichiita solder joint.Uchishandisa laser jenareta uye optical inotarisisa zvikamu zvewelding, yakakwira simba density, yakanyanya kupisa kupisa kunyatsoita, isingabatanidze welding, solder inogona kutengeswa paste kana tin waya, kunyanya yakakodzera kukwenenzvera majoini madiki munzvimbo diki kana majoini madiki ane simba rakaderera. , kuchengetedza simba.
3.Laser welding design zvinodiwa zvePCBA
(1) Otomatiki kugadzirwa PCBA kutapurirana uye chinzvimbo dhizaini
Nekugadzira otomatiki uye kuungana, iyo PCB inofanirwa kunge iine zviratidzo zvinoenderana nekumisikidzwa kwemaziso, seMako mapoinzi.Kana kuti mutsauko wepadhi uri pachena, uye kamera yekuona yakamira.
(2) Iyo welding nzira inosarudza marongerwo ezvikamu
Nzira imwe neimwe yekugadzira ine zvido zvayo zvekugadzirisa zvikamu, uye kurongeka kwezvikamu kunofanira kusangana nezvinodiwa zvekugadzirisa.Scientific uye inonzwisisika marongerwo anogona kuderedza akashata solder majoini uye kuderedza kushandiswa kwekushandisa.
(3) Dhizaini yekuvandudza welding pass-through rate
Kufananidza dhizaini yepadhi, solder kuramba, uye stencil Iyo padhi nepini chimiro chinotarisa chimiro chejoint yesolder uye zvakare inoona kugona kutora yakanyungudutswa solder.Iyo inonzwisisika dhizaini yegomba rekukwira inowana tin kupinda mwero we75%.
