2 Ungqimba lwe-FPC Flex PCB Circuit for Medical Infrared Analyzer

I-Case Study: I-infrared analyser idivayisi yezokwelapha enezingqimba ezi-2 ze-PCB eziguquguqukayo

Yethula:

Amabhodi e-PCB anezendlalelo ezi-2kumadivaysi ezokwelapha e-infrared analyzer ayizici ezibalulekile ekusebenzeni kwawo wonke kanye nokusebenza kocingo. Lokhu kuhlaziywa kwecala kuzogxila ezicini zezobuchwepheshe zomkhiqizo, okuhlanganisa ububanzi nobubanzi bomugqa, ukujiya kwebhodi, ukujiya kwethusi, indawo encane yokuvula i-flame retardant, ukuphathwa kwendawo, umbala wemaski ye-solder, ukuqina, njll. Izophinda igqamise izinhlelo zayo ezihlosiwe. kanye namadivayisi.

Uhlobo lomkhiqizo:

Ibhodi le-PCB elinezingqimba ezi-2Lo mkhiqizo uyibhodi le-PCB elinezingqimba ezi-2. Lawa maphaneli adizayinelwe ukuthi abe angasindi futhi aguquguquke, awenze alungele izinhlelo zokusebenza lapho amaphaneli edinga ukuhambisana nokuma okuthile noma ukungena ezindaweni eziqinile.

Ukucaciswa kobuchwepheshe:

Ububanzi Bomugqa kanye nesikhala:Ububanzi bomugqa webhodi le-PCB nobukhulu besikhala kubalulekile ekuqinisekiseni ubuqotho besignali efanele nokwethembeka. Kulesi sibonelo, ububanzi bomugqa buyi-0.12mm futhi ukuhlukaniswa komugqa ngu-0.1mm, okuqinisekisa ukunemba kokudluliswa kwesignali.

Ubukhulu bebhodi:Ubukhulu bebhodi obungu-0.15mm bunquma ukuguquguquka okuphelele nokuqina kwe-PCB. Lokhu kucatshangelwa kubalulekile ukuze kuqinisekiswe ukuthi ibhodi lingakwazi ukumelana nokucindezeleka okuhambisana nokugoba noma ukugoba ngaphandle kokuphazamisa ukusebenza kwalo.

Ukuqina Kwethusi:18um ugqinsi lwethusi kunikeza conductivity edingekayo ukuze udlulise amasignali yonkana PCB. Lokhu ukushuba kukhethwe ngokucophelela ukulinganisa ukuguquguquka nokuguquguquka kwebhodi jikelele.

Ubuncane bembobo ububanzi:Ubuncane bembobo ububanzi obungu-0.15mm bubhekisela kusayizi omncane wembobo ongabhojwa ku-PCB. Lokhu kunemba kubalulekile ukuze kufakwe izingxenye nokuqinisekisa ukuxhumana okufanele.

Ukuncipha komlilo:Ibanga le-flame retardant lifinyelela ku-94V0, okubonisa ukuthi impahla ye-PCB inokumelana nomlilo ophezulu futhi iyazicisha ngokwayo. Lokhu kubalulekile ekucatshangweni kokuphepha, ikakhulukazi ezinhlelweni zedivayisi yezokwelapha.

Ukwelashwa kwendawo:Ukwelashwa kwendawo yegolide ecwilisiwe kune-conductivity enhle kakhulu nokumelana nokugqwala. Iqinisekisa ukuxhumana okuthembekile nokuzinza kwesikhathi eside kwe-PCB.

Imibala Yemaski ye-Solder:Umbala ophuzi we-resistance welding ubonisa into ethile noma ukugqoka okusetshenziselwa inqubo yokushisela. Umbala ophuzi ungase ukhethwe ngenxa yezizathu zobuhle noma ukuhlukanisa indawo ethile ku-PCB.

Ukuqina:Ama-PCB aklanywe ngokuguquguquka engqondweni futhi inhlanganisela yezinto ingasetshenziswa ukufeza ukuqina okudingekayo. Kulokhu, izinto ezifana ne-PI (Polyimide) kanye ne-FR4 (I-Flame Retardant 4) ingasetshenziswa ukunikeza ibhalansi edingekayo phakathi kokuguquguquka nokuqinile.

Izinhlelo zokusebenza namadivayisi:Ibhodi le-PCB elinezingqimba ezi-2 eliklanyelwe ngokukhethekile okokusebenza kwezokwelapha kokuhlaziya infrared. Lawa madivayisi asebenzisa ubuchwepheshe be-infrared ukuze ahlaziye futhi alinganise amapharamitha ahlukahlukene kumasampula ezokwelapha. I-PCB eguquguqukayo yenza idivayisi ihlangane, ingasindi futhi yakhelwe ngokwe-ergonomically kukho kokubili izinhlelo zokusebenza zezokwelapha eziphathwayo nezimile.
