Iyo PCB yedunhu bhodhi solder mask process ndeimwe yeakakosha malink muPCB kugadzira maitiro, uye nyaya dzayo dzemhando ine zvakakosha pakuita uye kuvimbika kwePCB.Mune solder mask process, akajairika mhando matambudziko anosanganisira pores, nhema soldering, uye kuvuza.Aya matambudziko anogona kusangotungamira mukuderedzwa kwePCB kuita uye kuvimbika, asi anogona kuunza kurasikirwa kusingakoshi pakugadzira.Ichi chinyorwa chichasuma nzira dzinoshanda dzekugadzirisa matambudziko aya uye kuongorora mashandisirwo ePCB solder mask screen printing machines mukugadzirisa matambudziko aya.
1. Tsananguro yematambudziko akajairika emhando muPCB solder mask process
1. Stomata
Porosity ndeimwe yeakajairika mhando matambudziko muPCB solder mask process.Inonyanya kukonzerwa nekusakwana kupera kwegasi mune solder mask zvinhu.Aya ma pores anokonzeresa matambudziko akadai sekushaya simba kwemagetsi uye mapfupi maseketi muPCB panguva inotevera yekugadzirisa uye kushandiswa.
2. Virtual soldering
Welding inoreva kusabatana kwakashata pakati pePCB pads uye zvikamu, zvichikonzera kusagadzikana kwemagetsi kuita uye nyore kupfupika kana kuvhurika dunhu.Virtual soldering inonyanya kukonzerwa nekusakwana kunamatira pakati pe solder mask zvinhu uye padhi kana zvisina kufanira maitiro paramita.
3. Leakage
Leakage parikune kuvuza kwazvino pakati pemaseketi akasiyana paPCB kana pakati pedunhu nechikamu chakadzikwa.Leakage haingokanganisa mashandiro edunhu, asi inogona kukonzera nyaya dzekuchengetedza.Zvikonzero zvekudonha zvinogona kusanganisira nyaya dzemhando ine solder mask zvinhu, zvisina kufanira maitiro paramita, nezvimwe.
2. Solution
Kugadzirisa nyaya dzemhando yepamusoro, zvinotevera mhinduro dzinogona kutorwa:
Kune dambudziko rema pores, iyo yekuputira iyo solder inopikisa zvinhu inogona kuvandudzwa kuti ive nechokwadi chekuti zvinhu zvinopinda zvizere pakati pemitsara, uye pre-kubika nzira inogona kuwedzerwa kuti ibudise zvizere gasi mune solder resist material.Mukuwedzera, iwe unogonawo kuwedzera scraper pressure kugadzirisa mushure mekudhinda kwekrini kuti ubatsire kubvisa pores.Pano isu tinokurudzira kuti udzidze nezve hungwaru huzere otomatiki solder mask hole plugging muchina ine yayo yekudzvanya system.Ne 6 ~ 8 kg yegesi, inogona kubudirira Iyo scraper inogona kuzadza gomba nekurohwa kamwe chete uye kunyatsobudisa gasi.Iko hakuna chikonzero chekugadzirisa zvakare plug gomba kakawanda.Inoshanda, inochengetedza nguva uye dambudziko, uye inoderedza zvakanyanya chiyero chezvikara.
Kune dambudziko rekuona solder, maitiro anogona kuvandudzwa kuti ave nechokwadi chekunamatira kwakakwana pakati pe solder mask material uye pad.Panguva imwecheteyo, maererano nemaitiro ekugadzirisa, tembiricha yekubikira uye kudzvanywa kunogona kuwedzerwa zvakakodzera kuti ivandudze kunamatira pakati peiyo solder inopikisa zvinhu uye padhi.
Kune matambudziko ekudonha, iyo yemhando yekudzora solder resist zvinhu inogona kusimbiswa kuve nechokwadi kugadzikana kwemagetsi kuita.Panguva imwecheteyo, maererano nematanho ekugadzirisa, kupisa kwekubikira uye nguva inogona kuwedzerwa zvakakodzera kuti isimbise zvizere solder inopikisa zvinhu, nokudaro kuvandudza kushanda kwekudzivirira kwedunhu.
3. Kushandiswa kweXinjinhui PCB circuit board solder mask printing machine
Mukupindura kumatambudziko emhando yepamusoro, Xinjinhui PCB solder mask inogona kupa mhinduro dzinoshanda.Midziyo yacho inotora tekinoroji yekudhinda yepamberi, iyo inogona kunyatso kudzora huwandu hwekuputira uye chinzvimbo che solder mask zvinhu, zvinobudirira kudzivirira kuitika kwepores uye manyepo soldering.Panguva imwecheteyo, midziyo inewo yakangwara hurongwa hwekutonga basa, iyo inogona kukurumidza kushandura nhamba dzezvinhu mumaminitsi matatu kusvika ku5 pasina kudiwa kwekugadzirisa handwheel uye inobatanidza hungwaru hwakakwana hwekugadzirisa hurongwa kuti ive nechokwadi chokuti solder mask screen printing yakarurama uye inoshanda. .
Kudzidzira kwakaratidza kuti kushandiswa kweXinjinhui PCB redunhu bhodhi solder mask skrini yekudhinda muchina unogona zvinobudirira kuvandudza kunaka nekugadzirwa kwePCB solder mask process.Iko kushandiswa kwemudziyo uyu hakugone chete kuderedza kugadzirwa kwezvigadzirwa zvisina kukwana uye kuvandudza kugadzirwa kwakanaka, asi zvakare kupa vatengi zvigadzirwa zvePCB zvemhando yepamusoro kuti zvisangane nezvinodiwa zvakasiyana zvekushandisa.
4. Pfupiso
Ichi chinyorwa chinozivisa zvakajairika matambudziko emhando uye mhinduro muPCB solder mask process, inotarisa pakushandiswa kweXinjinhui PCB redunhu bhodhi solder mask skrini yekudhinda muchina mukugadzirisa matambudziko aya.Kudzidzira kwakaratidza kuti kushandiswa kwe solder resist kunogona kuvandudza kunaka uye kubudirira kwekugadzirwa kwePCB solder resist process, kuderedza kuitika kwezvigadzirwa zvisina kukwana, nekuvandudza kushanda kwekugadzira.Panguva imwecheteyo, midziyo iyi inogonawo kupa vatengi zvigadzirwa zvepamusoro zvePCB kuti zvisangane nezvinodiwa zvakasiyana zvekushandisa.Mhinduro uye nzira dzakatsanangurwa naXin Jinhui mune ino chinyorwa dzinogona kupa imwe referensi uye gwara kumabhizinesi akakodzera.
