Kunzwisisa rigid-flex circuit board bonding tekinoroji

suma:

Mune ino blog positi, isu tichaongorora zvakadzama nezve mabatirwo ari mugidhi-flex redunhu redunhu, tichiongorora nzira dzakasiyana dzinoshandiswa mukuita.

Rigid-flex circuit mabhodhi anozivikanwa mumaindasitiri akasiyana siyana anosanganisira aerospace, zvekurapa, uye zvemagetsi zvevatengi.Aya mabhodhi akasiyana nekuti anosanganisa flexible circuitry neakaomarara zvikamu, achipa kusimba uye kuchinjika.Chimwe chezvinhu zvakakosha izvo zvinogonesa kushanda uye kuvimbika kweakaomesesa-flex mabhodhi tekinoroji yekubatanidza inoshandiswa kubatanidza zvidimbu zvakasiyana.

1. Bonding tekinoroji:

Adhesive bonding tekinoroji inoshandiswa zvakanyanya mukuomarara-flex wedunhu bhodhi kugadzira.Inosanganisira kushandiswa kweanonamira yakasarudzika iyo ine kupisa kupisa mumiriri.Aya anonamira anoshandiswa kubatanidza flexible layers kune dzakaomarara zvikamu zvedunhu mabhodhi.Iyo yekunamatira haingopa rubatsiro rwechimiro chete asiwo inovimbisa kubatana kwemagetsi pakati pematanho.

Munguva yekugadzira, kunamatira kunoshandiswa nenzira inodzorwa uye zvidimbu zvakanyatsorongeka zvisati zvave laminated pamwe chete pasi pekupisa nekumanikidzwa.Izvi zvinosimbisa chisungo chakasimba pakati pezvikamu, zvichiita kuti rigid-flex circuit board ine yakanakisa mechanical uye magetsi zvinhu.

2. Surface Mount tekinoroji (SMT):

Imwe nzira yakakurumbira yekubatanidza rigid-flex circuit board layers iri kushandisa surface mount tekinoroji (SMT).SMT inosanganisira kuisa pamusoro pegomo zvikamu zvakananga pane yakaomesesa chikamu chedunhu bhodhi uye wozotengesa izvi zvikamu kumapadhi.Iyi tekinoroji inopa yakavimbika uye inobudirira nzira yekubatanidza mitsara paunenge uchiona kubatanidzwa kwemagetsi pakati pavo.

MuSMT, iwo akaomarara uye anochinjika akaturikidzana akagadzirwa aine vias anoenderana nemapadhi kuti afambise basa rekutengesa.Isa solder paste panzvimbo yepadhi uye isa chikamu chacho nemazvo.Bhodhi redunhu rinobva raiswa kuburikidza ne reflow soldering process, apo solder paste inonyunguduka uye inosanganisa zvidimbu pamwe chete, zvichigadzira chisungo chakasimba.

3. Kuburikidza negomba plating:

Kuti uwane yakawedzera simba remagetsi uye yekubatanidza magetsi, rigid-flex edunhu mabhodhi anowanzo shandisa kuburikidza-gomba plating.Iyo tekinoroji inosanganisira kuchera maburi mumitsetse uye kushandisa conductive material mukati memakomba iwayo.A conductive material (kazhinji mhangura) inopfekwa pamadziro egomba, kuve nechokwadi chisungo chakasimba uye kubatana kwemagetsi pakati pematanho.

Kuburikidza ne-gomba plating inopa imwe rutsigiro kune akaomesesa-flex mabhodhi uye inoderedza njodzi yeku delamination kana kutadza munzvimbo dzakanyanya-kushushikana.Kuti uwane mibairo yakanaka, maburi ekuboorera anofanirwa kunyatsomiswa kuti aenderane ne vias nemapadhi pamatanho akasiyana kuti uwane kubatana kwakachengeteka.

Mukupedzisa:

Iyo yekunamira tekinoroji inoshandiswa muakaomesesa-flex edunhu mabhodhi anoita basa rakakosha mukuona kutendeseka kwavo uye kushanda kwemagetsi.Adhesion, pamusoro pegomo tekinoroji uye kuburikidza-gomba plating nzira dzinoshandiswa zvakanyanya kubatanidza zvisingaite zvidimbu zvakasiyana.Tekinoroji yega yega ine zvayakanakira uye inosarudzwa zvichienderana nezvinodiwa zvePCB dhizaini uye mashandisiro.

Nekunzwisisa maitiro ekubatanidza anoshandiswa muakaomesesa-flex edunhu mabhodhi, vagadziri uye vagadziri vanogona kugadzira yakasimba uye yakavimbika magungano emagetsi.Aya mabhodhi epamusoro edunhu anosangana nezvinodiwa zvinokura zvehunyanzvi hwemazuva ano, zvichibvumira kushandiswa kwemagetsi anochinjika uye akasimba mumaindasitiri akasiyana.
