I-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, izinga lokubuyiswa komlilo, 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 futhi kuqinisekiswe 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) zingasetshenziswa 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.
