Kaihanga PCB Ahumahi me te PCBA
PCBA Ahumahi – Ngā papa hiko mō ngā mīhini whakahaere ahumahi
Ko te PCBA ahumahi, e mōhiotia ana ko te papa whakahaere ahumahi, he papa hiko i hangaia hei tu atu i te ru, te wiri, te pāmahana tino nui, te haumākū, me te puehu i roto i ngā taputapu ahumahi. E whakamahia ana tēnei PCBA hei mahi i ngā mahi maha i roto i te umanga whakahaere ahumahi. Kua hangaia hei whirihora i te hiko o tētahi kaupapa i roto i te āhua kiato, e āhei ai te rere tika o te iahiko i te ara e hiahiatia ana, ā, e whakarei ake ana i te mahi a te hua. He wāhanga nui hoki ēnei papa o ngā kaupapa me ngā taputapu whakahaere ahumahi, e āwhina ana ki te ine me te whirihora i ngā tawhā maha o te raina huihuinga, me te whiwhi i ngā rahinga ā-tinana tika.
Kamupene PCBA Taputapu Ahumahi – Richpcba
Mena kei te rapu koe i ngā papa PCB/PCBA whakahaere ahumahi kounga teitei i ngā utu e taea ana te utu, ko www.richpcba.com te mea pai rawa atu māu. I whakatūria ki Shenzhen, Haina i te tau 2004, he kaihanga huihuinga PCB mātou kua oti te whakarite, kua mahi ki ngā mano tini o ngā umanga o roto me tāwāhi i ngā tekau tau kua pahure ake nei. Kāore ā mātou ratonga hanga e herea noa ki te PCB me te PCBA; ka whakatinanahia hoki e mātou ngā whakaritenga motuhake, ngā mahi anō, me ngā whakarerekētanga e tonoa ana e ngā kiritaki kia pai ai ō rātou hiahia. Nā roto i ā mātou mahi ngaio me te wairua mahi pono, kua mōhiotia mātou e te tini o ngā kaihanga matua i te ao ahumahi.
He tohunga mātou ki te hanga PCB ahumahi maha-paparanga, ā, e whakarato ana i ngā ratonga PCBA kotahi-mutunga. Ka tīmata tā mātou tukanga me tētahi kōnae, Gerber rānei i tukuna mai e te kaiwhakamahi. Whai muri i te whiwhinga o tēnei kōnae, ka arotakehia e ā mātou miihini, ka whakatūria te tukanga hanga hei hanga papa PCB me ngā taonga PCBA mō te whakahaere ahumahi mā te whakamahi i ngā hangarau rerekē. Ka taea e RICHPCBA te whakatutuki i ngā hiahia o ngā kiritaki mō ngā kaupapa māmā ki te uaua, ngā puranga iti ki te huihuinga PCB nui, me ngā kamupene tīmatanga ki ngā kamupene nunui ahumahi. Ka whakahaerehia e tā mātou tīma tohunga ngā kaupapa mā roto i ngā kaiwhakahaere kaupapa 1V1, me te tautokona e ngā tīma hoko, miihini, hanga, me te whakahaere kounga.

Ngā Take Hoahoa PCB Ahumahi
Tahora Wāhanga
He mea nui te whakatakotoranga o ngā wāhanga ki runga i te papaaho hei whakaaroaro māu i te wā e hoahoa ana i ngā papaaho whakahaere ahumahi. Ka pāngia te pono me te mahi o te hua whakamutunga e te whakatakotoranga hē o ngā wāhanga. I te wā e hoahoa ana i te papaaho, me tino tupato kia whakauruhia ngā wāhanga ki runga i te papaaho me te iti rawa o te 100 mils te mokowā i waenga i ngā taha o te papaaho me ngā wāhanga kua mau. Mā tēnei ka whakarite kia ōrite ngā rahi o te papaaho me ngā kōhao kua mau.
EMI me te RFI
I roto i ngā mahi ahumahi, he mea nui kia whakaitihia ngā pānga o te Whakararuraru Hikohiko (EMI) me te Whakararuraru Auautanga Reo Irirangi (RFI), ka puta ai te haruru me te whakararuraru i te mahi a te PCBA. Hei whakatutuki i tēnei, he maha ngā rautaki a Rich PCBA:
Te tahora o te papa: Hei whakaiti i te tūponotanga o te hononga haruru, wehea ngā ara iahiko auau-tiketike mai i ngā ara iahiko auau-iti, ā, me pupuri kia matara atu ngā tohu mai i ngā papa hiko me ngā papa whenua. Me poto rawa ngā tohu tohu, ko ngā papa hiko me ngā papa whenua me nui rawa, ā, me whai hononga kōhao iti te ine i te hiko hei whakaiti i te aukati o te whatunga hiko.
Ngā wāhanga tātari: Tāpirihia ngā wāhanga tātari pērā i ngā pūnga iahiko me ngā inductors ki ngā raina hiko me ngā raina tohu hei tātari i te haruru kāore e hiahiatia.
Ngā Tikanga Whakatakoto Whenua me te Parepare: Kōpirihia ngā wāhanga tairongo ki roto i ngā whare herehere Faraday hei aukati i te EMI me te RFI.
Kōwhiringa Wāhanga: Kōwhiria ngā wāhanga o te papa hiko he kounga teitei te whakapūmau me te ārai. Whakamahia ngā taura ārai hei hono i te papa ki ngā taputapu o waho hei ārai i te hononga tohu kāore e hiahiatia.
Rauemi PCB Whakahaere Ahumahi
He mea nui te whiriwhiri i ngā rauemi mō te hanga PCB, ā, me ahu mai i te taiao mahi motuhake. Me kaha ngā rauemi mō ngā PCB e whakamahia ana i roto i te ahumahi ki te tu atu i ngā āhuatanga uaua, pērā i te pāmahana teitei, te ngaohiko teitei, te haumākū, te wiri, me te pānga matū. Ko ētahi o ngā rauemi e whakamahia whānuitia ana mō ngā PCB ahumahi ko:
● Pōrimirā: Ka taea e tēnei rauemi mahi-teitei te tu atu i ngā pāmahana tino kaha tae atu ki te 400°C, ā, he maha ngā wā e whakamahia ana i roto i ngā mahi rererangi, ngā mahi hōia, me ngā mahi whakahaere ahumahi pāmahana-teitei.
● Uku: He mea hanga te PCB uku ki te papa uku me ngā tohu konganuku. He tino pai te kawe wera, ā, ka taea te tu atu i ngā pāmahana teitei me ngā matū kino. He mea whakamahi noa i roto i ngā hikohiko mana me ngā tono auau teitei.
● PTFE: Ko te PTFE, te polytetrafluoroethylene rānei, he fluoropolymer he tino pai ōna āhuatanga ārai hiko e taea ai te tu atu i ngā pāmahana teitei tae atu ki te 260°C. He mea whakamahi noa i roto i ngā tono auau teitei me ngā tono ngaruiti, tae atu ki ngā taiao matū kino.
● FR-4: Ko tēnei rauemi hiato i hangaia mai i te kakahu muka karāhe whatu me te kapia epoxy te rauemi e whakamahia whānuitia ana mō ngā PCB whānui, tae atu ki ngā ahumahi. He pai ngā āhuatanga ārai hiko o te PCB FR4, ā, ka taea e ia te tu atu ki ngā pāmahana teitei me ngā matū.
