Chenjezo pa Kusindikiza Kwa Bodi la PCB: Kalozera wa Solder Mask Ink

Tsegulani:

Pamene kupanga kusindikizidwa matabwa dera (PCBs), kugwiritsa ntchito zipangizo zoyenera ndi njira n'kofunika kuonetsetsa ntchito mulingo woyenera ndi kudalirika. Chofunika kwambiri pakupanga kwa PCB ndikugwiritsa ntchito inki ya solder mask, yomwe imathandizira kuteteza mikwingwirima yamkuwa ndikuletsa milatho yogulitsira pamisonkhano. Komabe, kuti mupeze zotsatira zabwino zosindikizira bolodi la PCB, njira zina zodzitetezera ziyenera kutsatiridwa.Mu positi iyi ya blog, tikambirana njira zodzitetezera zomwe ziyenera kuganiziridwa pogwira inki ya solder mask, kufotokoza zinthu zofunika kwambiri kuti mukhalebe wapamwamba komanso magwiridwe antchito.

1. Sankhani inki yoyenera ya solder:

Kusankha inki yoyenera ya solder ndikofunikira kuti mukwaniritse zodalirika komanso zogwirizana. Momwemo, inki yosankhidwayo iyenera kupereka zomatira kwambiri pa PCB pamwamba, kukhala ndi kutentha kwakukulu, komanso kukhala ndi mphamvu zabwino zamagetsi. Zinthu monga gawo lapansi la board board, zofunikira pakupanga, ndi mawonekedwe a PCB omwe amafunidwa ayenera kuganiziridwa popanga chisankho chovuta ichi.

2. Kusunga ndi kasamalidwe koyenera:

Inki ya chigoba cha solder ikapezeka, kusungidwa koyenera ndi kusamalira ndikofunikira kuti izi zitheke. Ndikoyenera kusunga inki pamalo ozizira, owuma kutali ndi kuwala kwa dzuwa komanso kutentha kwambiri. Onetsetsani kuti chidebecho chatsekedwa pamene sichikugwiritsidwa ntchito kuti musawume kapena kuipitsidwa ndi inki. Njira zoyenera zogwirira ntchito, monga kuvala magolovesi ndi kusamala kuti musatayike ndi kukhudza khungu, ziyenera kugwiritsidwa ntchito kutsimikizira chitetezo chaumwini ndi kusunga kukhulupirika kwa inki.

3. Chithandizo chapamwamba:

Kukwaniritsa inki ya inki ya solder kumafuna kukonzekera bwino pamwamba. Musanagwiritse ntchito inki, pamwamba pa PCB iyenera kutsukidwa kuchotsa zonyansa zilizonse monga fumbi, mafuta, kapena zidindo za zala. Njira zoyenera zoyeretsera, monga kugwiritsa ntchito zotsukira zapadera za PCB ndi nsalu zopanda lint, ziyenera kugwiritsidwa ntchito kuti pakhale paukhondo. Zotsalira zilizonse zotsalira kapena zonyansa zomwe zatsala pa bolodi zidzasokoneza kumamatira ndi ntchito yonse ya inki.

4. Kuganizira za chilengedwe:

Mikhalidwe ya chilengedwe imakhala ndi gawo lofunikira pakuwonetsetsa kuti inki yogulitsira ikugwiritsidwa ntchito bwino. Zinthu monga kutentha ndi chinyezi ziyenera kuyang'aniridwa ndi kuyang'aniridwa mkati mwa magawo omwe atchulidwa ndi wopanga inki. Kuchuluka kapena kusinthasintha kwachilengedwe kungakhudze kukhuthala kwa inki, nthawi yowumitsa ndi zomatira, zomwe zimapangitsa kuti pakhale zotsatira zoyipa zosindikiza. Kuwongolera pafupipafupi kwa zida zowongolera zachilengedwe kumalimbikitsidwa kuti zisungidwe zofunikira panthawi yonse yakupanga kwa PCB.

5. Ukadaulo wogwiritsa ntchito:

Kugwiritsa ntchito bwino inki ya solder mask ndikofunikira kuti mukwaniritse zotsatira zomwe mukufuna. Ganizirani kugwiritsa ntchito zida zongochitika zokha monga makina osindikizira pazenera kapena njira za inkjet kuti muwonetsetse kuti zikuwonekera bwino komanso mosasintha. Samalani kuti mugwiritse ntchito inki yokwanira kuti mutsimikizire kufalikira, koma osati makulidwe ambiri. Kuwongolera koyenera kwa inki, kuthamanga kwa skrini, ndi kuthamanga kwa squeegee (pankhani yosindikiza pazenera) zimathandizira kulembetsa molondola ndikupewa zolakwika monga ma pinholes, kutuluka magazi, kapena kutsekereza.

6. Kuchiritsa ndi kuyanika:

Gawo lomaliza pakugwiritsa ntchito inki ya solder mask ndikuchiritsa ndi kuyanika. Tsatirani malangizo a wopanga kutentha koyenera ndi nthawi yofunikira kuti inki ichire bwino. Pewani kutentha kapena kuziziritsa mwachangu chifukwa izi zingayambitse kupsinjika kapena kuchepetsedwa kwa wosanjikiza wa inki wochiritsidwa. Onetsetsani nthawi yowuma yokwanira musanapitirize ndi njira zopangira zotsatila monga kuika chigawo kapena soldering. Kusunga kusasinthasintha pakuchiritsa ndi kuyanika magawo ndikofunikira kuti mupeze chigoba chokhazikika komanso cholimba cha solder.

Pomaliza:

Pochita ndi solder chigoba inki, kutenga njira zofunika pa PCB bolodi kusindikiza ndondomeko n'kofunika kuonetsetsa apamwamba, odalirika ndi okhalitsa zotsatira. Posankha mosamala inki yolondola ya solder mask, kuchita zosungirako ndi kusamalira moyenera, kukonzekera bwino pamwamba, kulamulira zinthu zachilengedwe, kugwiritsa ntchito njira zolondola zogwiritsira ntchito, ndikutsatira njira zochiritsira ndi kuyanika, opanga amatha kupanga ma PCB opanda cholakwika pamene akusunga ndondomeko yopangira kugwirizana. Kutsatira kusamala kumeneku kumatha kukulitsa luso lamakampani opanga ma PCB, kuchepetsa zolakwika, ndikuwonjezera kukhutira kwamakasitomala.
