Kodi Kodi Zimayambitsa Of Pcb kuwotcherera Zotayikira Pa Aluminiyamu gawo lapansi PCB | YMS

Pofuna kutsimikizira mtundu wonse wa aluminiyamu gawo la PCB , kuti solder yapamwamba kwambiri iyenera kugwiritsidwa ntchito pakupanga kukonza magwiridwe antchito a PCB ndikuletsa warpage ndi defect.So, kodi zimayambitsa zolakwika za PCB pa gawo la aluminium ndi chiyani? Tsatirani akatswiri opanga ma aluminium PCB a Yongmingsheng kuti mumvetse.

1. Kubowoleza kwa dzenje kwa bolodi la dera kumakhudza mtundu wa kuwotcherera.

Chifukwa cha kusasunthika koyipa kwa dzenje la bolodi, padzakhala zopindika zowotcherera, zomwe zimakhudza magawo azigawozo, zomwe zimayambitsa zigawozo ndi gawo lamkati la kusakhazikika kwa mzere, zomwe zimapangitsa kugwiranso ntchito kwa dera .

2.Welding zopindika chifukwa cha warping.

Dera loyendetsa dera ndi zinthu zina zimayimitsidwa, ndipo kupsinjika ndi kusokonekera kudzatsogolera pakuwotcherera, kufupika kwazing'ono ndi zina zolakwika.Warping nthawi zambiri imayamba chifukwa cha kutentha kwapakati pakati pamagawo apamwamba ndi otsika a bolodi. polypropylene, bolodi limapindika chifukwa cha kulemera kwake.

3. Kapangidwe ka bolodi la dera limakhudza mtundu wa kuwotcherera.

Kuchokera pamalingaliro amapangidwe, kukula kwa board board ndikokulirapo, ngakhale kuwotcherera kumakhala kosavuta kuwongolera, koma mzere wosindikizidwa ndiwotalikirapo, kuchuluka kwa impedance kumawonjezeka, mtengo ukuwonjezeka; Kukula kwake ndikocheperako, kutaya kwamoto kwachepetsedwa, kuwotcherera si kophweka kulamulira, ndi kulowererana mwagwirizana wa mizere mozungulira n'zosavuta kuchitika.

Kotero kapangidwe ka bolodi la PCB liyenera kukhathamiritsidwa:

A. Imachepetsa kulumikizana pakati pazigawo zapamwamba kwambiri ndikuchepetsa kusokonekera kwamagetsi.

B. Pazinthu zolemera, zikonzeni ndi mabokosi kenako ndikuwatsitsira.

C. Zotentha zimayenera kuonedwa ngati kutentha kwa thupi, zotenthetsera ziyenera kukhala kutali ndi komwe zimatulutsa kutentha.

D. Zidazi zimakonzedwa mofananira momwe zingathere, zomwe sizabwino kokha, komanso zosavuta kusungunuka komanso zoyenera kupanga. Makonzedwe abwino kwambiri oyendetsera dera ndi rectangle 4 rect3. mwadzidzidzi ndipo pewani kugwiritsa ntchito madera akuluakulu amkuwa.

Zomwe zili pamwambazi ndizomwe zimayambitsa zolakwika mu PCB ya gawo la aluminium. Tikukhulupirira kuti zitha kukhala zothandiza kwa inu.Ndife ochokera ku China gawo la aluminium gawo - Yongmingsheng Electronics, takulandirani kuti mufunse!

Kusaka kokhudzana ndi zotayidwa gawo lapansi PCB:
