X射線檢測設(shè)備為新能源汽車鋰電安全護(hù)盾

最近，關(guān)于鋰電池爆炸的新聞層出不窮，即便是正規(guī)廠家生產(chǎn)的鋰電池也不能確保一定安全。近年來越來越普及的純電動汽車，已經(jīng)讓鋰電的安全問題不再僅限于手機(jī)、平板電腦等“用”的方面，鋰電池在“行”方面的安全問題也慢慢凸顯。無論是“用”還是“行”，鋰電行業(yè)給消費(fèi)者帶來便利生活的前提和核心，是它的安全性。對于鋰電池，導(dǎo)致爆炸的原因復(fù)雜：運(yùn)輸過程中的碰撞、存儲時環(huán)境溫度和濕度不符合標(biāo)準(zhǔn)都是……

X射線對于壓鑄件常見內(nèi)部缺陷的檢測

鑄造是現(xiàn)代機(jī)械制造工業(yè)的基礎(chǔ)工藝之一，具有成本低廉、一次成形以及可以制造復(fù)雜結(jié)構(gòu)大型件等優(yōu)點(diǎn)，被廣泛應(yīng)用于汽車零部件、機(jī)械制造、電子、醫(yī)療器械、鐘表儀器、五金產(chǎn)品、航空航天等工業(yè)生產(chǎn)的眾多領(lǐng)域。鑄造作為重要的機(jī)械工業(yè)的基礎(chǔ)行業(yè)，在信息高速發(fā)展的現(xiàn)如今，提高鑄造的生產(chǎn)加工效率、生產(chǎn)質(zhì)量，將是廣大鑄造工作者的必須要面臨的課題。歷來鑄件毛坯產(chǎn)品廢品率居高不下是行業(yè)各種鑄造方法的通病，怎樣……

X-Ray在BGA焊接質(zhì)量檢測的應(yīng)用

BGA的全稱是Ball Grid Array(球柵陣列結(jié)構(gòu)的PCB)，是一種大型組件的引腳封裝方式，與 QFP的四面引腳相似，都是利用SMT錫膏焊接與電路板相連。其不同處是羅列在四周的"一度空間"單排式引腳，如鷗翼形伸腳、平伸腳、或縮回腹底的J型腳等;改變成腹底全面數(shù)組或局部數(shù)組，采行二度空間面積性的焊錫球腳分布，做為芯片封裝體對電路板的焊接互連工具。它具有封裝面積少,功能加大，引腳數(shù)目增多,可靠性高,電性能好，整體成本低等特點(diǎn)。雖然BGA器件有諸多方面的優(yōu)點(diǎn)，但仍存在
