PCBA Short Circuit Magani matsala

Da zarar an kammala ƙirar PCB, muna buƙatar duba shi don duk fasalin aikin.Kamar yadda idan muka gama takardar jarabawar da kanmu, sai mu yi bincike mai sauki sannan mu sake duba duk matsalolinta, ta yadda ba za mu yi babban kuskure ba saboda sakaci.Masu kera neoden masu ɗorawa masu zuwa don yin bayanin yadda ake magance PCBA sarrafa gajeriyar laifuffuka masu alaƙa da ilimin.

1. Bude ƙirar PCB akan kwamfutar, cibiyar sadarwar gajeriyar hanya tana haskakawa, duba abin da wuri ya fi kusa, mafi kusantar haɗi zuwa yanki.Kula da hankali na musamman ga gajeren kewaye na ciki na IC.Idan manual soldering, don bunkasa kyawawan halaye:.

2. Kafin a siyar da ku duba allon PCB da hannu sau ɗaya, kuma amfani da multimeter don bincika maɓallin kewayawa (musamman wutar lantarki da ƙasa) ko gajeriyar kewayawa.

3. Duk lokacin da bayan walda guntu don amfani da multimeter don auna wutar lantarki da ƙasa ko akwai gajeriyar kewayawa.

4. PCBA samar soldering lokaci ba su jujjuya baƙin ƙarfe, bazata fling da solder zuwa guntu ta soldering ƙafa (musamman tebur sitika aka gyara), shi ne ba sauki sami wani short-circuit sabon abu.Ɗauki allo don yanke layin (musamman wanda ya dace da allon Layer guda ɗaya/biyu), yanke layin bayan kowane ɓangare na tubalan aikin ya sami kuzari, kuma a hankali an kawar da su.

5. Yin amfani da kayan aikin bincike na gajeren lokaci.

6. PCBA guntu sarrafa BGA guntu, saboda duk solder gidajen abinci suna rufe da guntu ganuwa, da Multi-Layer Board (fiye da 4 yadudduka), to, shi ne mafi kyau ga raba wutar lantarki a cikin zane na kowane guntu, tare da. wani Magnetic bead ko 0 ohm lantarki sun dangane, don haka da cewa akwai wutar lantarki tare da wani gajeren kewaye zuwa ƙasa, cire haɗin da Magnetic bead ganewa, yana da matukar sauki ƙayyade tsara zuwa guntu.Saboda wahala na BGA soldering, manual waldi, idan ba a yi hankali ba zai kasance kusa da wutar lantarki da ƙasa biyu solder bukukuwa short-circuited.

7. Small-sized table sticker capacitor waldi dole ne a yi hankali, musamman ma wutar lantarki tace capacitor (103 ko 104), babban lamba, yana da sauƙi don haifar da wutar lantarki da ƙasa takaice.
