走字燈箱全都花了

我做了第一個(gè)走字燈箱可是剛開始還好，只有幾個(gè)地方有不該著的燈著了，我仔細(xì)檢查發(fā)現(xiàn)有的燈珠用萬用表量全通了！估計(jì)是在加工的時(shí)候被靜電擊穿了！我開是換，換了大概有100多個(gè)（我做的是16X96的）可是還完后更花了，我現(xiàn)在都不知道是什么原因，我在檢查時(shí)發(fā)現(xiàn)幾乎所有的燈都壞了！我現(xiàn)在不知道是什么原因，請大家?guī)兔φ艺以颍?/td>

看看是不是什么地方絕緣沒有搞好，引入了市電了

老大詳細(xì)說說，我以后也可以注意啊

仔細(xì)檢查過了！發(fā)現(xiàn)多數(shù)燈擊穿了！更換后問題解決！但是不知道為什么會(huì)擊穿，我估計(jì)是靜電太大了！目前我沒辦法解決！

呵呵，不是沒辦法解決，估計(jì)你什么地方引入了市電，只是你沒有覺察出來

應(yīng)該不是壞了，我也遇到過 我這個(gè)跟你那個(gè)一摸一樣的效果 不過 我把背板去掉 敞開著就沒事！

新手問題多多，我好害怕啊，不敢入手了都。

學(xué)習(xí)中,多檢查,多總結(jié),不要急著通電.

是的,沒錯(cuò),多檢查,不要急著通電.

多看論壇，做的時(shí)候仔細(xì)點(diǎn)，先做小點(diǎn)的，不然虧大發(fā)了

我做的每個(gè)都會(huì)出現(xiàn)燒毀的情況，郁悶

是不是電烙鐵絕緣不好了？

測量輸出電壓了沒有，是否正常 1# 丹頂鶴

學(xué)習(xí)中,多檢查,多總結(jié),不要急著通電

學(xué)習(xí)啦，新手入門！好怕怕哦

好可怕啊?。。。。。?！
