Inteko ya Flex PCB Itandukanye Ninteko ya Rigid PCB Mubikorwa byo Gukora

Inteko ya PCB (Icapiro ryumuzunguruko) nigice cyingenzi mubikorwa bya elegitoroniki. Harimo inzira yo gushiraho no kugurisha ibikoresho bya elegitoronike kuri PCB. Hariho ubwoko bubiri bwingenzi bwinteko za PCB, inteko zoroshye za PCB hamwe ninteko zikomeye za PCB. Mugihe byombi bikora intego imwe yo guhuza ibice bya elegitoroniki, bikozwe muburyo butandukanye.Muri iyi blog, tuzaganira uburyo inteko ya flex PCB itandukanye ninteko ikomeye ya PCB mubikorwa byo gukora.

1. Inteko ya FPC:

Flex PCB, izwi kandi nka PCB yoroheje, ni ikibaho cyumuzunguruko gishobora kugororwa, kuzunguruka cyangwa kugoreka kugirango gihuze imiterere nuburyo butandukanye.Itanga inyungu nyinshi kurenza PCBs, nko kugabanya umwanya wo gukoresha umwanya hamwe no kuramba. Uburyo bwo gukora inteko ya flex PCB ikubiyemo intambwe zikurikira:

a. Igishushanyo cya PCB cyoroshye: Intambwe yambere mugiterane cyoroshye cya PCB ni ugushushanya imiterere yumuzunguruko.Ibi bikubiyemo kumenya ingano, imiterere n'iboneza bya flex PCB. Hibanzwe cyane ku gutondekanya ibimenyetso byumuringa, vias na padi kugirango habeho guhinduka no kwizerwa.

b. Guhitamo ibikoresho: PCB yoroheje ikozwe mubikoresho byoroshye nka polyimide (PI) cyangwa polyester (PET).Guhitamo ibikoresho biterwa nibisabwa muri porogaramu, harimo kurwanya ubushyuhe, guhinduka, hamwe nubukanishi.

c. Gukora umuziki: Gukora PCB byoroshye birimo inzira nka Photolithography, etching, na electroplating.Photolithography ikoreshwa muguhindura imirongo yumuzingi kuri substrate yoroheje. Etching ikuraho umuringa udakenewe, usize umuzenguruko wifuza. Isahani ikorwa kugirango yongere imbaraga kandi irinde imirongo.

d. Gushyira ibice: Mubiterane bya flex PCB, ibice bishyirwa kumurongo woroshye ukoresheje tekinoroji yo hejuru (SMT) cyangwa ikorana buhanga.SMT ikubiyemo gushiraho ibikoresho bya elegitoronike hejuru yubuso bwa PCB bworoshye, mugihe tekinoroji yo mu mwobo ikubiyemo kwinjiza inzira mu mwobo wabanje gucukurwa.

e. Kugurisha: Kugurisha ni inzira yo guhuza ibikoresho bya elegitoronike na PCB yoroheje.Ubusanzwe ikorwa hifashishijwe uburyo bwo kugurisha ibintu cyangwa kugurisha umuyaga, bitewe n'ubwoko bw'ibigize n'ibisabwa guterana.

2. Inteko ya PCB ikomeye:

PCBs zikomeye, nkuko izina ribigaragaza, ni imbaho ​​zumuzunguruko zidashobora guhinduka cyangwa kugoreka.Bakunze gukoreshwa mubikorwa aho ihame ryimiterere ari ngombwa. Igikorwa cyo gukora inteko ikomeye ya PCB itandukanye ninteko ya flex PCB muburyo butandukanye:

a. Igishushanyo cya PCB Rigid: Igishushanyo cya PCB gisanzwe cyibanda ku kugabanya ubwinshi bwibigize no guhuza ubunyangamugayo bwibimenyetso.Ingano, umubare wibice, hamwe nuburyo bwa PCB bigenwa ukurikije ibisabwa.

b. Guhitamo ibikoresho: PCB zikomeye zakozwe hifashishijwe insimburangingo nka fiberglass (FR4) cyangwa epoxy.Ibi bikoresho bifite imbaraga zubukanishi hamwe nubushyuhe bwumuriro kandi birakwiriye mubikorwa bitandukanye.

c. Ibihimbano byumuzunguruko: Ibihimbano bya PCB bikubiyemo intambwe isa na flex PCBs, harimo gufotora, gufata, no gufata.Ariko, ibikoresho byakoreshejwe hamwe nubuhanga bwo guhimba birashobora gutandukana kugirango bikomere byubuyobozi.

d. Gushyira ibice: Ibigize bishyirwa kuri PCB itajegajega ukoresheje SMT cyangwa ikorana buhanga, bisa ninteko ya flex PCB.PCBs zikomeye, ariko, zemerera ibintu byinshi bigoye kuboneza ibice bitewe nubwubatsi bukomeye.

e. Igurisha: Igikorwa cyo kugurisha inteko ikomeye ya PCB isa niy'inteko ya flex PCB.Nyamara, tekinike yihariye nubushyuhe bukoreshwa birashobora gutandukana bitewe nibikoresho bigurishwa.

Mu mwanzuro:

Iterambere ryoroshye rya PCB hamwe ninteko ikomeye ya PCB ifite uburyo butandukanye bwo gukora bitewe nuburyo butandukanye bwibikoresho nibisabwa.PCB ihindagurika itanga ihinduka kandi iramba, mugihe PCB zikomeye zitanga imiterere ihamye. Kumenya itandukaniro riri hagati yubwoko bubiri bwinteko za PCB ni ngombwa muguhitamo uburyo bukwiye bwa porogaramu runaka ya elegitoroniki. Urebye ibintu nkibintu bifatika, ibisabwa byubukanishi no guhinduka, ababikora barashobora kwemeza imikorere myiza no kwizerwa kwinteko za PCB.
