Zigawo zoteteza ndi zida za 8-wosanjikiza PCB kuteteza kuwonongeka ndi kuipitsidwa

Momwe mungasankhire wosanjikiza woyenera ndi zophimba za PCB ya 8-wosanjikiza kuti mupewe kuwonongeka kwakuthupi ndi kuipitsidwa kwa chilengedwe?

Chiyambi:

M'dziko lothamanga kwambiri la zida zamagetsi, ma board osindikizira (PCBs) amagwira ntchito yofunika kwambiri. Komabe, zigawo zolondola izi zimatha kuwonongeka ndi chilengedwe komanso kuwonongeka kwa chilengedwe. Kuonetsetsa moyo wautali komanso magwiridwe antchito abwino, ndikofunikira kusankha wosanjikiza woyenera woteteza ndi zinthu zokutira za PCB yanu ya 8-wosanjikiza. Mubulogu ino, tikambirana za momwe tingasankhire zinthu zofunika izi, makamaka kupewa kuwononga thupi komanso kuwononga chilengedwe.

Kupewa kuwonongeka kwakuthupi:

1. Ganizirani makulidwe ndi zinthu zachitetezo chachitetezo:
Pankhani yoteteza PCB ya 8-wosanjikiza ku kuwonongeka kwakuthupi, makulidwe ndi zinthu zachitetezo ndizofunika kwambiri. Chitetezo chokulirapo chimapereka kukana bwino kukhudzidwa ndi kupsinjika kwamakina. Moyenera, gawo loteteza liyenera kupangidwa ndi zinthu zolimba monga polyimide kapena FR-4 zomwe zimatha kupirira mphamvu zakunja.

2. Unikani momwe zida zoyambira zimagwirira ntchito:
Kuwonjezera pa chitetezo chotetezera, zipangizo zophimba zimathandizanso kwambiri kuteteza kuwonongeka kwa thupi. Ndikofunikira kusankha chivundikiro chokhala ndi mphamvu zambiri. Zida monga acrylic ndi polycarbonate zimapereka kukana kwabwino kwambiri, kuteteza ma PCB ku madontho mwangozi kapena tokhala.

3. Sankhani njira yokutira:
Kuyika chophimba chapadera pa PCB ya 8-wosanjikiza ndi njira yabwino yowonjezeramo chitetezo chowonjezera pakuwonongeka kwakuthupi. Zovala zochiritsika ndi UV, zokutira zofananira, ndi zokutira za silikoni ndizosankha zotchuka. Zovala izi zimagonjetsedwa ndi abrasion, mankhwala, chinyezi ndi fumbi.

Kupewa ndi kuwononga chilengedwe:

1. Gwiritsani ntchito zida zoteteza chilengedwe:
Kuipitsa chilengedwe ndi vuto lofulumira kwambiri m’dziko lamakonoli. Posankha zigawo zodzitchinjiriza ndi zophimba za ma PCB a 8-wosanjikiza, ndikofunikira kusankha zida zoteteza chilengedwe. Yang'anani zipangizo zopanda mankhwala owopsa monga lead, mercury, ndi heavy metal. Sankhani zinthu zomwe zimagwirizana ndi miyezo ya RoHS (Restriction of Hazardous Substances) kuti muchepetse kuwononga chilengedwe ndikulimbikitsa chitukuko chokhazikika.

2. Yang'anani njira zopakira:
Encapsulation ndi njira yabwino kwa 8-wosanjikiza PCB kuteteza kuipitsa chilengedwe. Poyika PCB yanu ndi zida zapadera, mumapanga chotchinga ku chinyezi, fumbi, dzimbiri, ndi zowononga zina zachilengedwe. Potting mankhwala, epoxies, ndi silikoni ndi wamba encapsulation zipangizo zodziwika ndi zoteteza katundu.

3. Ganizirani njira zosindikizira:
Kuphatikizira makina osindikizira mu mapangidwe a 8-layer PCB kungalepheretse kuipitsidwa kwa chilengedwe. Ma gaskets opangidwa ndi zinthu monga neoprene kapena EPDM angapereke chotchinga chogwira ntchito motsutsana ndi chinyezi ndi fumbi. Kuphatikiza apo, matepi okhala ndi zida zabwino kwambiri zosindikizira atha kugwiritsidwa ntchito kukulitsa njira yosindikizira.

Pomaliza:

Kusankha wosanjikiza woyenera woteteza ndi zophimba za PCB ya 8-wosanjikiza ndikofunikira kuti mupewe kuwonongeka kwakuthupi komanso kuipitsidwa kwa chilengedwe. Poganizira zinthu monga makulidwe, zida, kukana kwamphamvu komanso kuyanjana ndi chilengedwe, mutha kutsimikizira moyo wautali komanso magwiridwe antchito oyenera azinthu zamagetsi izi. Kumbukirani, PCB yotetezedwa bwino sikuti imangowonjezera moyo wake komanso imalimbikitsa machitidwe okhazikika pochepetsa kuwononga chilengedwe.Malingaliro a kampani Shenzhen Capel Technology Co., Ltd.analiyokhazikitsidwa mu 2009.Ma PCB osinthikandiMa PCB olimba-Flexmphamvu yopanga imatha kufika kuposa450000 sqm pamwezi.
