style="text-indent:25px">航空插頭與線纜焊接的方法航空插頭與線纜焊接的方法或許很多人還不是很清楚，豐年科技針對(duì)這個(gè)問(wèn)題為大家搜集了一些航空插頭焊接的資料，供大家參考學(xué)習(xí)。安裝在PCB板航空插頭一般為表面貼裝或通孔安裝。表面安裝的焊針必須正確定位、尺寸合適、與PCB板完全共面或者可以微浮以適應(yīng)PCB板上的所有錫盤(pán)，保證焊接有充分的強(qiáng)度、過(guò)程質(zhì)量和電路的可靠性.穿孔的焊針必須準(zhǔn)確定位，尺寸合適，均衡放置，并具備良好的可焊性，這樣有利于插入和焊接。在整個(gè)裝配過(guò)程中必須經(jīng)得起熱處理產(chǎn)生的高溫沖擊，在焊接中主要采用紅外預(yù)熱和對(duì)流預(yù)熱使熱量傳導(dǎo)至焊針和錫盤(pán)界面以熔化焊錫膏。接下來(lái)不必***要求清洗，但人們一般期望清洗。預(yù)熱區(qū)的溫度一般設(shè)定為峰值230°C，幾分鐘后溫度更高。同波峰焊接一樣，突如其來(lái)的高溫常常使端子熔化、扭曲、起泡和變形。焊接條件有***的區(qū)別，這取決于航空插頭的類(lèi)型和焊接過(guò)程的步驟。適用于波峰焊接、安裝在PCB板上的航空插頭是典型的穿孔安裝型。穿孔的焊針必須準(zhǔn)確定位，尺寸合適，均衡放置，并具備良好的可焊性，這樣有利于插入和焊接。河北四芯防水連接器貨真價(jià)實(shí)</p><div
