4 Layers Flexible PCB Prototype ya Medical Blood Pressure Chipangizo

Nkhani Yophunzira

Capel's Advanced Circuits Flex PCB ndi 4-layer flexible printed circuit board (PCB) yopangidwira mwapadera zida zachipatala.Imagwiritsidwa ntchito makamaka pazida za kuthamanga kwa magazi.

Chogulitsachi chimakhala ndi zatsopano zambiri zaukadaulo kuti zithandizire kukulitsa magwiridwe antchito ake pamsika wa zida zamankhwala.

Nambala ya Masanjidwe:
Mapangidwe a 4-wosanjikiza a PCB akuwonetsa kuchuluka kwazovuta komanso magwiridwe antchito. Pophatikiza zigawo zingapo, ma PCB amatha kukhala ndi zozungulira zozungulira, zomwe zimalola kufalitsa ma siginecha bwino komanso kuchepa kwapang'onopang'ono. Mbali yatsopanoyi imatsimikizira kulondola ndi kudalirika kwa kuyeza kwa magazi.
Kutalikirana kwa mizere ndi kutalika kwa mizere:
Ndi makulidwe a mizere ndi kutalika kwa mizere ya 0.12 mm ndi 0.15 mm motsatana, PCB yosinthika ya Capel imawonetsa luso lochititsa chidwi la miniaturization. Mipata yocheperako komanso mipata imapangitsa kuti mabwalo ovuta amangidwe m'malo ang'onoang'ono, zomwe zimapangitsa kuti zida zachipatala zikhale zazing'ono komanso kunyamula.
Makulidwe a board:
Kukula kwa mbale zoonda kwambiri za 0.2mm ndi luso lina laukadaulo laukadaulo wa Capel. Mbiri yaying'onoyi imalola ma PCB osinthika kuti azitha kuphatikizidwa mosavuta pamapangidwe a zida zazing'ono zamankhwala popanda kusokoneza kulimba kapena kukhazikika.
Makulidwe a Copper:
Makulidwe amkuwa a 35μm amatsimikizira kusinthika kwabwino komanso kunyamula kokwanira pano. Pokhala ndi gawoli, PCB yosinthika ya Capel imatha kutumiza ndikugawa ma sign amagetsi ofunikira pakuyezera kuthamanga kwa magazi. Zimachepetsanso kutaya mphamvu ndi kutentha kwa kutentha, zomwe zimathandiza kuti zipangizo zachipatala ziziyenda bwino.
Kabowo kakang'ono:
Kukula kochepa kwa kabowo ndi 0.2mm, kusonyeza kulondola kwakukulu kwa mapangidwe ndi kupanga. Kupanga kwaukadaulo kumeneku kumathandizira kulumikizana kolondola kwambiri, kumachepetsa chiopsezo cha kusokoneza kwa ma sign kapena kulephera.
Zoletsa moto:
94V0 flame retardant grade imatsimikizira kuti PCB yosinthika imakwaniritsa miyezo yolimba yachitetezo chamakampani azachipatala. Izi ndizofunikira chifukwa zimalepheretsa ma PCB kuyatsa kapena kufalitsa moto, kuteteza ogwiritsa ntchito ndi zida zachipatala ku zoopsa zomwe zingachitike.
Chithandizo cha Pamwamba:
Kumizidwa pamwamba pa golide kumapangitsa kuti zinthu ziziyenda bwino komanso zimateteza mizere yamkuwa kuti isachite dzimbiri. Kupanga kwaukadaulo kumeneku kumakulitsa moyo wautumiki wa ma PCB osinthika ndikuwonetsetsa kukhazikika kwa kulumikizana kwamagetsi, ngakhale m'malo ovuta azachipatala. Mtundu wa Mask wa Solder:
Kugwiritsiridwa ntchito kwa black resistance soldering color sikumangopereka kukongola kwa mankhwala komanso kumagwira ntchito ngati chizindikiro chowonetsera kusiyanitsa PCB yosinthika panthawi ya msonkhano. Kuyika kwa utoto kumeneku kumathandizira kupanga zinthu mosavuta ndikuchotsa kuthekera kwa zolakwika pakuyika chigawo ndi kugulitsa.

Kuti apititse patsogolo ntchito ndi zida, Capel akuwona zosintha zotsatirazi:

Kusinthasintha kowonjezereka:
Pamene zipangizo zachipatala zimakhala zosavala komanso zomasuka, kuonjezera kusinthasintha kwa ma PCB osinthika kungathandize kusakanikirana kosasinthika ndi zipangizozi. Pogwiritsa ntchito zida zatsopano komanso njira zopangira, Capel imatha kukulitsa luso lopindika la ma PCB osinthika popanda kusokoneza magwiridwe antchito kapena kudalirika kwawo.
Thinner circuit board design:
Kuphatikiza pa makulidwe ang'onoang'ono a bolodi, kuchepetsanso makulidwe a ma PCB osinthika kungapereke maubwino owonjezera pakuchepetsa thupi komanso kusinthasintha kowonjezereka. Kupita patsogolo kumeneku kudzathandiza kupanga zida zazing'ono, zomasuka bwino zachipatala kwa odwala.
Kuphatikiza matekinoloje apamwamba:
Capel ikhoza kuthandizira chitukuko cha zipangizo zamakono zamakono mwa kuphatikiza matekinoloje apamwamba monga kugwirizanitsa opanda zingwe, masensa ndi mphamvu zogwiritsira ntchito deta mu ma PCB osinthika. Kupanga kwaukadaulo kumeneku kumathandizira kuyang'anira deta munthawi yeniyeni, kupititsa patsogolo chidziwitso cha odwala ndikukulitsa luso lozindikira.
