對(duì)于小型針孔件來說,如果在機(jī)加工序完畢后不能立即采用三氯乙烯超聲波除油清洗,那么接下來的常規(guī)鍍前處理很難將孔內(nèi)干涸的油污除凈,這樣孔內(nèi)的鍍層結(jié)合力就會(huì)大大降低.。</span></p> <p style="text-indent: 2em; line-height: 2.5em;"> <strong><span

在鍍細(xì)長(zhǎng)形狀插針時(shí),如果按通常使用遙電流密度電鍍時(shí),針尖部位的鍍層會(huì)比針桿上厚許多,在放大鏡下觀察針尖有時(shí)會(huì)旦火柴頭形狀.(見圖3)其頭頸部的鍍層即插針前端頂部靠后一點(diǎn)部位的金鍍層檢驗(yàn)結(jié)合力就不合格.這種現(xiàn)象在振動(dòng)鍍金時(shí)易出現(xiàn)。</span></p>

為了保證接插件的插孔在插孔在插拔使用時(shí)具有一定彈性,在產(chǎn)品設(shè)計(jì)時(shí)大多數(shù)種類的插孔都有是在口部設(shè)計(jì)一道劈槽.在電鍍過程中鍍件不斷翻動(dòng)部份插孔就在開口處互相插在一起致使對(duì)插部位電力線互相屏敝造成孔內(nèi)電鍍困難。</span></p> <p style="text-indent: 2em;

由于在插孔的劈槽底部距孔底還有一段距離,這段距離客觀上形成了一段盲孔.同樣在插針和插孔的焊線孔里也有這樣一段盲孔,它是提供導(dǎo)線焊接時(shí)的導(dǎo)向作用.當(dāng)這些孔的孔徑較小(往往低于1毫米甚至低于0.5毫米)而盲孔濃度超過孔徑時(shí)鍍液很難流進(jìn)孔內(nèi),流進(jìn)孔內(nèi)的鍍液又很難流出,所以孔內(nèi)的金層質(zhì)量很難保證。</span></p>

當(dāng)接插件體積較小時(shí)相對(duì)來說單槽鍍件的總表面積就較大,這樣在鍍小型針孔件時(shí)如果單槽鍍件較多.原來的陽極面積就顯得不夠.特別是當(dāng)鉑鈦網(wǎng)使用時(shí)間過長(zhǎng)鉑損耗太多時(shí),陽極的有效面積就會(huì)減少,這樣就會(huì)影響鍍金的深鍍能力,鍍件的孔內(nèi)就會(huì)鍍不進(jìn)。
