4 Layers Flexible PCB Prototype for Medical Blood Pressure Device

Case Study

Capel's Advanced Circuits Flex PCB yog 4-txheej flexible printed circuit board (PCB) tshwj xeeb uas tsim los rau cov khoom siv kho mob.Nws yog siv rau hauv cov khoom siv ntshav siab.

Cov khoom no suav nrog ntau qhov kev tsim kho thev naus laus zis los txhim kho nws cov kev ua tau zoo thiab kev ua haujlwm hauv kev lag luam khoom siv kho mob.

Number of Layers:
Lub 4-txheej tsim ntawm PCB qhia txog qib siab ntawm kev nyuaj thiab kev ua haujlwm. Los ntawm kev sib koom ua ke ntau cov khaubncaws sab nraud povtseg, PCBs tuaj yeem ua raws li cov khoom siv hluav taws xob, uas tso cai rau kev sib kis tau zoo dua thiab txo cov lus sib tham. Cov yam ntxwv tshiab no ua kom qhov tseeb thiab kev ntseeg siab ntawm kev ntsuas ntshav siab.
Kab dav thiab kab sib nrug:
Nrog cov kab dav thiab kab sib nrug ntawm 0.12 hli thiab 0.15 hli feem, Capel's saj zawg zog PCB qhia tau tias muaj peev xwm ua tau zoo. Cov kab me me thiab qhov sib txawv ua rau cov kab hluav taws xob ua kom yooj yim ua rau hauv qhov chaw me me, tso cai rau cov khoom siv kho mob ua me me thiab nqa tau yooj yim dua.
Board thickness:
Lub ultra-thin phaj thickness ntawm 0.2 hli yog lwm qhov kev tsim kho tshiab ntawm Capel qhov kev txawj ntse. Qhov profile slim no tso cai rau cov PCBs hloov tau yooj yim rau hauv kev tsim cov khoom siv kho mob me me yam tsis muaj kev cuam tshuam rigidity lossis durability.
Copper thickness:
35μm tooj liab thickness kom zoo conductivity thiab txaus tam sim no nqa peev xwm. Nrog rau qhov ntsuas no nyob rau hauv qhov chaw, Capel's saj zawg zog PCB tuaj yeem xa tawm tau zoo thiab faib cov hluav taws xob teeb liab uas xav tau rau kev ntsuas ntshav siab. Nws kuj tseem txo cov hluav taws xob poob thiab hluav taws xob tsim hluav taws xob, pab txhim kho tag nrho cov khoom siv kho mob.
Yam tsawg kawg nkaus aperture:
Qhov tsawg kawg nkaus aperture loj yog 0.2 hli, qhia qhov siab precision ntawm kev tsim thiab kev tsim khoom. Qhov kev tsim kho thev naus laus zis no ua rau muaj kev sib txuas hauv Circuit Court ntau dua, txo qhov kev pheej hmoo ntawm cov teeb liab cuam tshuam lossis tsis ua haujlwm.
Nplaim retardant:
94V0 nplaim hluav taws retardant qib ua kom ntseeg tau tias cov PCB hloov tau raws li cov qauv kev nyab xeeb nruj ntawm kev kho mob kev lag luam. Cov yam ntxwv no yog qhov tseem ceeb vim tias nws tiv thaiv PCBs los ntawm qhov hluav taws kub los yog kis hluav taws, tiv thaiv cov neeg siv khoom thiab cov khoom siv kho mob los ntawm kev phom sij.
Kev kho deg:
Immersed kub saum npoo kho txhim kho conductivity thiab tiv thaiv tooj liab kab los ntawm corrosion. Qhov kev tsim kho thev naus laus zis no txuas ntxiv kev pabcuam lub neej ntawm cov PCBs hloov tau yooj yim thiab ua kom muaj kev ruaj ntseg ntawm kev sib txuas hluav taws xob, txawm tias nyob rau hauv qhov chaw kho mob hnyav. Solder Mask Xim:
Kev siv cov xim dub kuj tsis yog tsuas yog muab kev zoo nkauj rau cov khoom xwb tab sis kuj tseem ua rau pom qhov muag pom qhov sib txawv ntawm qhov hloov pauv PCB thaum sib dhos. Cov xim coding no yooj yim rau kev tsim cov txheej txheem thiab tshem tawm qhov ua yuam kev hauv kev tso kawm thiab soldering.

Txhawm rau txhim kho kev lag luam thiab khoom siv ntxiv, Capel txiav txim siab txog kev txhim kho hauv qab no:

Txhim khu kev yooj yim:
Raws li cov khoom siv kho mob tau dhau los ua kev hnav-tiv taus thiab xis nyob, ua kom yooj yim ntawm cov PCBs hloov tau tuaj yeem ua rau muaj kev sib txuam nrog cov khoom siv no. Los ntawm kev siv cov ntaub ntawv tshiab thiab cov txuj ci tsim khoom, Capel tuaj yeem ua rau muaj peev xwm khoov ntawm PCBs hloov tau yam tsis muaj kev cuam tshuam lawv cov kev ua tau zoo lossis kev ntseeg siab.
Thinner Circuit Board tsim:
Ntxiv nrog rau qhov slim Circuit board thickness, ntxiv txo cov thickness ntawm saj zawg zog PCBs tuaj yeem muab cov txiaj ntsig ntxiv ntawm kev txo qhov hnyav thiab ua kom yooj yim dua. Qhov kev nce qib no yuav pab txhim kho cov khoom siv kho mob me me, yooj yim dua rau cov neeg mob.
Kev koom ua ke ntawm advanced technologies:
Capel tuaj yeem pab txhawb kev txhim kho cov cuab yeej kho mob ntse los ntawm kev sib koom ua ke cov thev naus laus zis xws li kev sib txuas wireless, sensors thiab cov ntaub ntawv ua cov peev txheej rau hauv cov PCB hloov tau. Qhov kev tsim kho thev naus laus zis no yuav ua rau muaj kev saib xyuas cov ntaub ntawv hauv lub sijhawm, txhim kho cov neeg mob kev paub dhau los thiab txhim kho lub peev xwm kuaj mob.
