Chengetedzo yePCB Board Kudhinda: Nhungamiro yeSolder Mask Ink

suma:

Paunenge uchigadzira akadhindwa edunhu mabhodhi (PCBs), kushandisa zvinhu zvakanaka uye hunyanzvi hwakakosha kuti uve nechokwadi chekushanda kwakanaka uye kuvimbika. Chinhu chakakosha chekugadzirwa kwePCB ndiko kushandiswa kweingi ye solder mask, iyo inobatsira kuchengetedza mhangura yemhangura uye kudzivirira mabhiriji anotengeswa panguva yekuungana. Nekudaro, kuti uwane akakwana PCB board ekudhinda mhinduro, mamwe matanho ekudzivirira anofanirwa kuteverwa.Mune ino blog post, isu tichakurukura zvinodikanwa zvekuchengetedza izvo zvinofanirwa kutariswa kana uchibata solder mask ingi, kutsanangura zvakakosha zvinhu kuchengetedza yakakwirira mhando uye kushanda.

1. Sarudza yakakodzera solder mask inki:

Kusarudza iyo chaiyo solder mask inki kwakakosha kuti uwane yakavimbika uye inowirirana kupera. Sezvineiwo, iyo inki yakasarudzwa inofanirwa kupa yakanakisa adhesion kune PCB pamusoro, ine yakanyanya kupisa inopikisa, uye ine yakanaka magetsi ekudzivirira zvivakwa. Zvinhu zvakadai sedhigirii bhodhi substrate, magadzirirwo ekugadzira zvinodiwa, uye anodiwa PCB maitiro anofanirwa kutariswa pakuita iyi sarudzo yakaoma.

2. Kuchengetedza uye kubata kwakakodzera:

Kana solder mask inki yawanikwa, kuchengetedza kwakaringana uye kubata kwakakosha kuchengetedza kuita kwayo. Inokurudzirwa kuchengeta inki munzvimbo inotonhorera, yakaoma kure nechiedza chezuva uye kuchinja kwakanyanya kwekushisa. Ita shuwa kuti mudziyo wakavharwa kana usingashandiswe kudzivirira kuoma kana kusvibiswa kweinki. Matanho akakodzera ekubata, akadai sekupfeka magirovhosi uye kutora matanho ekudzivirira kurasika uye kubata kweganda, anofanirwa kushandiswa kuve nechokwadi chekuchengetedzwa kwemunhu uye kuchengetedza kuvimbika kweinki.

3. Kurapwa kwepamusoro:

Kuwana yakakwana solder mask inki application inoda kunyatso gadzirira kwepamusoro. Usati waisa inki, nzvimbo yePCB inofanira kucheneswa kubvisa chero tsvina yakaita seguruva, girisi, kana zvigunwe. Nzira dzekuchenesa dzakafanira, dzakadai sekushandisa michina yePCB yekuchenesa nemachira asina lint, dzinofanirwa kushandiswa kuve nechokwadi chekuti pakachena. Chero zvimedu zvakasara kana tsvina yasara pabhodhi inozokanganisa kunamatira uye kuita kwese kweinki.

4. Kufunga nezvezvakatipoteredza zvinhu:

Mamiriro ezvakatipoteredza anoita basa rakakosha mukuona kuti yakakwana solder mask inki application. Zvinhu zvakadai setembiricha nehunyoro zvinofanirwa kunyatsotariswa uye kudzorwa mukati mezvikamu zvakatarwa zvakatsanangurwa nemugadziri weinki. Kunyanya kana kushanduka kwemamiriro ekunze kunogona kukanganisa inki viscosity, nguva yekuomesa uye adhesion zvivakwa, zvichikonzera kutadza kudhinda mhedzisiro. Kugara kurongeka kwemidziyo yekudzora nharaunda inokurudzirwa kuchengetedza mamiriro anodiwa mukati mePCB yekugadzira maitiro.

5. Tekinoroji yekushandisa:

Kushandiswa kwakaringana kwengiki yemasiki ye solder kwakakosha kuti uwane mhedzisiro inodiwa. Funga kushandisa michina yemagetsi yakaita semichina yekutsikisa skrini kana nzira dzeinkjet kuti uve nechokwadi chekuvharirwa chaiko uye kunoenderana. Ngwarira kuisa ingi yakaringana kuti uone kuvharika kwakakwana, asi kwete kukora zvakanyanya. Kudzora kwakaringana kwekuyerera kweinki, kudzvanya kwescreen, uye kudzvanywa kwechidzitiro (munyaya yekudhinda skrini) kuchabatsira kuwana kunyoresa chaiko uye kudzivirira hurema hwakaita semapinho, kubuda ropa, kana bhiriji.

6. Kurapa nekuomesa:

Nhanho yekupedzisira mune solder mask inki application process ndeye kurapa nekuomesa. Tevedzera zvinongedzo zvemugadziri zvetembiricha yakakodzera uye nguva inodiwa kuti ingi irape zvinobudirira. Dzivisa kukurumidza kupisa kana kutonhora sezvo izvi zvinogona kukonzera kusagadzikana kana delamination yeakapora inki layer. Iva nechokwadi chekuomesa nguva yakakwana usati waenderera mberi nemaitiro anotevera ekugadzira akadai sechikamu chekuisa kana soldering. Kuchengetedza kuenderana mukurapa nekuomesa ma paramita kwakakosha kuti uwane yunifomu uye yakasimba solder mask.

Mukupedzisa:

Paunenge uchibata nemasolder mask inks, kutora matanho anodiwa panguva yePCB board kudhinda maitiro kwakakosha kuti uve nechokwadi chemhando yepamusoro, yakavimbika uye inogara kwenguva refu. Nekunyatsosarudza iyo chaiyo solder mask inki, kudzidzira kuchengetedza uye kubata kwakaringana, kugadzirira zvakaringana pamusoro, kudzora zvakatipoteredza, kushandisa nzira dzekushandisa dzakaringana, uye nekutevera zvinokurudzirwa kurapa nekuomesa maitiro, vagadziri vanogona kugadzira maPCB asina chaanopomerwa asi vachichengetedza maitiro ekugadzira anoenderana. Kuomerera kune idzi dziviriro kunogona kuwedzera zvakanyanya kugona kwePCB yekugadzira indasitiri, kuderedza hurema, uye kuwedzera kugutsikana kwevatengi.
