Tuhinga o mua PCB ngawari ngawari kaore e taea te whakahawea ki te hanga PCB. Ko tetahi take ko te ia ki te whakaititanga. Hei taapiri, ko te hiahia mo te PCBS maro mārō kei te piki ake na te ngawari me te mahinga o te huihuinga 3D. Heoi, kaore e taea e nga kaihanga PCB katoa te whakatutuki i nga mahi hangai PCB uaua me te uaua. Ko nga papa huringa taarua-taapiri e hangaia ana e tetahi mahinga e whakaiti ana i te matotoru o te papa pakari ki te 0.25mm +/- 0.05mm. Ma tenei, ka ahei te poari ki te whakamahi i nga tono e hiahia ana kia piko te papa me te whakauru ki roto i te whare. The plate can be used for one-time bending installation and multi-bending installation.

Anei tetahi tirohanga o etahi huanga e motuhake ana:

FR4 haurua – ngawari te hanga PCB

L Ko te huanga tino nui e pai ana hei mahi maau ake ko te ngawari me te urutau ki te waahi waatea.

L Ko tona rereketanga kua piki ake na te mea na tona ngawari kaore e aukati i tana whakawhiti tohu.

L He maamaa ano hoki.

I te nuinga, ko te PCBS haangai-ngawari hoki e mohiotia ana mo te utu nui na te mea he hototahi a raatau mahinga whakangao me nga kaha o nga mahi hanga.

L Ka tiakina e ratau te wa hoahoa me te waa huihuinga.

L He whirinaki tino pono raatau, ehara i te mea nui na te mea ka karo ratou i nga raru, tae atu ki nga taapiri me nga taera.

Tikanga hanga PCB

The main manufacturing process of FR4 semi-flexible printed circuit board is as follows:

Ko te mahinga e hipoki ana i nga ahuatanga e whai ake nei:

L Tapahi rauemi

L Uwhi kiriata maroke

L Tirohanga aunoatanga aunoanoa

L Browning

L laminated

L whakamātautau X-hihi

L keri

L hiko hiko

L Tahuringa whakairoiro

L etching

L Taarua mata

L Te whakaatu me te whanaketanga

L Whakaoti mata

L Te mira whakahaere hohonu

L Whakamatau hiko

L Mana kounga

L tākai

He aha nga raru me nga rongoa ka taea i te mahi PCB?

Ko te raru nui ki te mahi whakangao kia mau ki nga manawanui o te mira whakahaere hohonu. He mea nui ano hoki kia kore e pakaru nga kapiti, te pupuhi hinu ranei ka raru pea te kounga. Ko tenei ko te tirotiro i nga mea e whai ake nei i te wa o te mira whakahaere hohonu:

L matotoru

L ihirangi Whakapaa

L Te huri i te manawanui

Te whakamatautau mira whakahaere hohonu A

Ko te mira matotoru i mahia ma te mahere mahere kia rite ki te matotoru o 0.25 mm, 0.275 mm me 0.3 mm. Whai muri i te tukunga o te poari, ka whakamatautauria mehemea ka tu pakari 90 nekehanga. Ko te tikanga, mena ko te toenga ko te 0.283mm, ka kiia te muka karaihe kua kino. Therefore, the thickness of the plate, the thickness of the glass fiber and the dielectric condition must be taken into account when conducting deep milling.

Te whakamātautau mira whakahaere hohonu B

I runga i nga korero o runga ake nei, me whakarite te matotoru parahi o te 0.188mm ki te 0.213mm i waenga i te paparanga aukati me te L2. Me tika te tiaki mo nga pakanga katoa ka pa, ka pa ki te ahua o te matotoru.

Te whakamatautau mira whakahaere hohonu C

He mea nui te mira whakahaere i te hohonu kia mohio ai kua whakatauhia nga waahanga ki te 6.3 “x10.5” whai muri i te tukunga o te tauira. After this, survey point measurements are taken to ensure that 20 mm vertical and horizontal intervals are maintained.

Special fabrication methods ensure that the depth control thickness tolerance is within ±20μm.
