Ko bhodhi regungano rePCB richakuvadza muviri wemunhu here?

Will thePCB musanganobhodhi kukuvadza muviri wemunhu?Shamwari zhinji dzakashanyira musangano dzichabvunza mibvunzo yakadai.Nhasi ndichakupa mhinduro!Zvinokuvadza kushanda kwenguva yakareba muPCB board environment.PCB kusvibiswa kwegungano kunoreva chero madhipoziti epasi, tsvina, slag inclusions uye adsorbents inoderedza makemikari, emuviri kana magetsi zvimiro zvePCBA kusvika kumazinga asina kukodzera.

Njodzi dzekusvibiswa kwePCBA, dzinogona kutungamira zvakananga kana zvisina kunanga kumusangano wePCB zvinogona kuitika njodzi, semuenzaniso:

1. Iyo organic asidhi iri mune zvakasara ichasvibisa PCBA;

2. Munguva yesimba-pakugadzirisa, ions mune zvakasara zvinokonzera electromigration nekuda kwekusiyana kunogona kuitika pakati pezvibatanidza zvekutengesa, zvichiita kuti kukundikana kwechigadzirwa kupfupi;

3. Zvisaririra zvinokanganisa maitiro ekuputira;

4. Mushure menguva uye kuchinja kwekushisa kwezvakatipoteredza, kuputika uye kuputika kwekuputira kunokonzera matambudziko nekuvimbika kwechigadzirwa.

PCB kusvibiswa kwegungano kunoreva chero tsvina yepasi, madhipoziti, adsorbents uye slag inclusions inoderedza kemikari, yemuviri kana yemagetsi zvimiro zvePCBA kusvika kumazinga asina kukodzera.Kuti uvandudze kuvimbika uye kunaka kwezvigadzirwa zvemagetsi, zvinodikanwa kunyatso kudzora kuvepo kwezvisaririra panguva yekugadziriswa kwePCB, uye izvi zvinosvibisa zvinofanirwa kubviswa zvachose kana zvichidikanwa.

Iko kusvibiswa kwePCB musangano kunonyanya kusanganisira zvinotevera zvinhu:

1. PCB gungano pamusoro kusvibiswa kuchakonzerwa nekusvibiswa kana oxidation yePCB gungano zvikamu uyePCB redunhu mabhodhi;

2. Manual soldering ichagadzirwa zvigunwe, uye wave soldering ichagadzirwa imwe Wave soldering trace uye Welding tray (fixture) trace.Panogona kunge paine mamwe marudzi ezvinosvibisa paPCB gungano repamusoro mumadhigirii akasiyana, akadai seplugging glue, tepi yekupisa yakasara glue, zvigunwe uye guruva;

3. Mukugadzira PCB musangano wekugadzira, zvakakosha kushandisa solder paste, welding wire ye welding.Flux inoburitsa zvakasara panguva yekushambadzira, ichisvibisa pamusoro pePCB bhodhi regungano, uye ndiyo inonyanya kusvibisa;

4. Kusvibiswa kweElectrostatic kunokonzerwa neguruva, mvura uye chiutsi chinonyungudutsa, chiutsi, organic organic matter uye zvimedu zvinochajiswa zvakanamirwa paPCB musangano munzvimbo yebasa.

Isu tine chivimbo mukukupa iwe yakanakisa musanganiswa wekutendeuka-kiyi PCB gungano sevhisi, mhando, mutengo uye nguva yekutumira mune yako Diki batch vhoriyamu PCB gungano rekodhi uye Mid batch Vhoriyamu PCB musangano wehurongwa.

Kana iwe uchitsvaga yakanakaPCB musangano mugadziri, ndapota tumira mafaera ako eBOM uye mafaera ePCB kusales@pcbfuture.com.Ese mafaera ako akavanzika zvakanyanya.Tichakutumira quote chaiyo ine nguva yekutungamira mumaawa makumi mana nemasere.
