Mugihe cyihuta cyiterambere rya tekinoroji yubuvuzi, icyifuzo cyibikoresho bikora neza nicyo cyambere. Muri ibyo bice, FPCs yagaragaye nkibintu byingenzi mubikorwa bitandukanye, cyane cyane mubice byimyororokere yumuriro wa kimuntu. Iyi ngingo irasobanura akamaro ka 2L FPC hamwe na polyimide (PI) na FR4 stiffeners, ikora ubushakashatsi kubyo basabye mubuvuzi, ibiranga inzitizi zikomeye, hamwe nubworoherane nubwinshi batanga.
Gusobanukirwa 2L FPC
FPCs ningirakamaro muri elegitoroniki igezweho, itanga igisubizo cyoroheje kandi cyoroshye kubice bihuza. FPC igizwe na 2 igizwe nibice bibiri byayobora bitandukanijwe na substrate insulateri, byemerera ibishushanyo mbonera byumuzingi mugihe bikomeza guhinduka. Kwishyira hamwe kwa stiffeners, nka PI na FR4, byongera imiterere yimikorere yiyi mizunguruko, bigatuma ikoreshwa muburyo butandukanye, harimo nibikoresho byubuvuzi.
PI Gukomera: Guhitamo-Ibikorwa Byinshi
Polyimide (PI) ni polymer ikora cyane izwiho kuba ihagaze neza yubushyuhe, imiti irwanya imiti, hamwe nubukanishi. Iyo ikoreshejwe nka stiffener muri 2L FPCs, PI itanga ibyiza byinshi:
Ubushyuhe bwumuriro: PI irashobora kwihanganira ubushyuhe bwo hejuru, bigatuma biba byiza mubisabwa birimo kubyara ubushyuhe, nka sensor ya infragre.
Kurwanya imiti: Mubidukikije byubuvuzi, ibikoresho bikunze guhura nimiti itandukanye. Kurwanya PI kumashanyarazi nindi miti ituma kuramba no kwizerwa byumuzunguruko.
Impedance: Imiterere ya dielectric ya PI igira uruhare murwego rwo hejuru rwimbogamizi, zikaba ingirakamaro kubikorwa byoroshye nka sensor ya termopile isaba ibipimo nyabyo.
FR4 Gukomera: Ubundi buryo butandukanye
FR4 nikintu gikoreshwa cyane mubikoresho bikozwe muri fibre yububiko hamwe na epoxy resin. Azwiho imbaraga za mashini hamwe nuburyo bwo gukwirakwiza amashanyarazi. Iyo ushyizwemo nka stiffener muri 2L FPCs, FR4 itanga inyungu zitandukanye:
Imbaraga za mashini: FR4 itanga inkunga ikomeye, ituma ikoreshwa mubisabwa aho kuramba ari ngombwa.
Ikiguzi-Cyiza: Ugereranije na PI, FR4 muri rusange ihendutse, bigatuma ihitamo neza kubakora ibicuruzwa bashaka guhuza imikorere nibiciro.
Dutandukanye mubisabwa: FR4 ihindagurika ituma ikoreshwa mubikoresho bitandukanye byubuvuzi, kuva mubikoresho byo gusuzuma kugeza kubikoresho byo kuvura.
Gusaba murwego rwubuvuzi
Kwishyira hamwe kwa 2L FPCs hamwe na PI na FR4 stifeners byafunguye inzira nshya mubuvuzi, cyane cyane mugutezimbere ibyuma bifata ibyuma bya termo-infile. Izi sensor ni ingenzi kubipimo byo gupima ubushyuhe budahuye, nibyingenzi mubikorwa bitandukanye byubuvuzi, harimo:
1. Kumenya umuriro
Nyuma y’ibibazo by’ubuzima ku isi, ubushobozi bwo kumenya vuba na neza umuriro bwabaye ingirakamaro. Ibyuma bifata ibyuma bya infragre ya muntu, ukoresheje 2L FPCs hamwe na PI na FR4, bitanga ubushyuhe bwihuse kandi bwizewe butabanje guhura, bigabanya ibyago byo kwanduzanya.
2. Gukurikirana abarwayi
Gukomeza gukurikirana ibimenyetso byingenzi by’abarwayi ni ngombwa mu bihe bikomeye byo kwita ku barwayi. Ihinduka rya 2L FPCs ryemerera guhuza sensor ya thermopile mubikoresho byambara, bigafasha ubushyuhe bwigihe. Ibiranga impedance nyinshi byemeza gusoma neza, nibyingenzi mumutekano wumurwayi.
3. Ibikoresho byo kubaga
Mubidukikije byo kubaga, ibisobanuro ni urufunguzo. 2L FPCs hamwe na PI na FR4 stiffeners irashobora kwinjizwa mubikoresho byo kubaga kugirango itange ibitekerezo byubushyuhe bwigihe, byemeze ko ibikoresho bikomeza kubushyuhe bwiza mugihe gikwiye.
4. Gukurikirana ibidukikije
Usibye gusaba ubuvuzi butaziguye, ibyuma byifashishwa bya infrrafile byumuntu birashobora gukoreshwa mugukurikirana ibidukikije mubuzima. Mugupima ubushyuhe bwibidukikije, ibyo byuma bifasha birashobora kugumana ibihe byiza mubyumba byo gukoreramo no gukira abarwayi.
Imikorere ihanitse kandi ihindagurika
Ihuriro rya PI na FR4 stiffeners muri 2L FPCs itanga uruvange rwihariye rwimikorere ihanitse kandi yoroheje. Ubu buryo bubiri-bukomeye butuma ababikora bahuza ibishushanyo byabo kugirango babone ibisabwa byihariye. Kurugero, mubihe aho kurwanya ubushyuhe bukabije ari ngombwa, PI irashobora gushyirwa imbere, mugihe FR4 irashobora gukoreshwa mubisabwa aho imbaraga za mashini ari ngombwa.
Ibiranga Impedance Yinshi
Ibiranga impedance biranga 2L FPCs hamwe na PI stiffeners bifite akamaro kanini mubisabwa bisaba ibipimo byoroshye. Mu byuma byifashishwa bya infrarafarike ya kimuntu, impedance nyinshi ituma ibimenyetso bike bitakaza kandi bikanonosorwa neza, bikaba ngombwa mugusoma ubushyuhe bwizewe. Ibi biranga ingenzi cyane mugupima ubuvuzi, aho ibisobanuro bishobora kugira ingaruka zikomeye kubisubizo byabarwayi.
Ibinyuranye mubishushanyo
Ubwinshi butangwa na 2L FPCs hamwe na PI na FR4 stiffeners butuma ibishushanyo mbonera bishobora guhuza nibikorwa bitandukanye byubuvuzi. Ababikora barashobora gukora ibisubizo byihariye byujuje ibyifuzo byibikoresho bitandukanye, byongera imikorere nibikorwa. Uku guhuza n'imihindagurikire y'ikirere ni ingenzi mu buryo ikoranabuhanga rihora ritera imbere, kandi hakenewe ibisubizo bishya bigenda byiyongera.
