一、PCB覆銅板隨著電子產(chǎn)品向輕、薄、小、高密度、多功能方向發(fā)展，印制電路板上元器件的組裝密度和集成度越來(lái)越高，功耗也越來(lái)越高， 對(duì)PCB基板的散熱要求越來(lái)越迫切。 如果基板散熱不好，會(huì)導(dǎo)致印刷電路板上元器件過(guò)熱，從而降低整機(jī)的可靠性。 在此背景下，高散熱金屬PCB基板應(yīng)運(yùn)而生。鋁基覆銅板是應(yīng)用最廣泛的金屬PCB基板。 該產(chǎn)品于1969年由日本三洋國(guó)策發(fā)明，1974年開(kāi)始應(yīng)用于STK系列功率放大混合集成電路。80年代初期，我國(guó)金屬基覆銅板主要用于軍工產(chǎn)品。 當(dāng)時(shí)金屬PCB基板材料完全依賴進(jìn)口，價(jià)格昂貴。

PCBA proofing is the most frequently asked question in our customer consultation. Can you make samples with PCBA? What is the minimum quantity you can sample? Of course, there are also many new customers do not know much about PCBA template. Now do you kn
PCBA是PCB電路板制造、元器件采購(gòu)與檢驗(yàn)、SMT貼片加工、插件加工、程序燒制、測(cè)試、老化等一系列加工工序。
PCBA板本質(zhì)上屬于生產(chǎn)過(guò)程。 PCB空板經(jīng)過(guò)SMT上片或經(jīng)過(guò)DIP插件的全制程。
PCBA proofing refers to the trial production of printed circuit boards before mass production. It is mainly used in the process of small batch trial production to the circuit board factory after the electronic engineer has planned the circuit, which is ca
