過硫酸鈉在PCB行業的一般應用--微蝕!

發布來源:http://www.mybuildingdesignz.com    更新時間:2023-01-06 點擊數:

隨著5G時代的發展,PCB(PrintedCircuitBoard)行業的發展一定也隨之壯大,而PCB作為電子元器件的核心支撐載體,所需要用到的原材料非常多,包括過硫酸鈉在內的各種化學物料。不過很多雖然知道PCB行業需要用到過硫酸鈉,但是具體如何就不清楚,這很常見,因為這其中可能會涉及一些技術問題。而今天氫氧化鉀廠家要和大家講的是過硫酸鈉在PCB行業的一般應用——微蝕!
With the development of 5G era, the development of PCB (Printed Circuit Board) industry must also grow. As the core support carrier of electronic components, PCB needs a lot of raw materials, including various chemical materials such as sodium persulfate. However, although many people know that the PCB industry needs sodium persulfate, they do not know how to use sodium persulfate. This is very common, because it may involve some technical problems. Today,  wants to talk about the general application of sodium persulfate in PCB industry -- micro etching!
線路板分為單層與多層,多層線路板有內層和外層之分。如手機、電腦主板等等要用到多層的線路板以縮小體積。內層線路在線路板的中間,所以內層線路不要求外觀,而強調功能。
The circuit board is divided into single layer and multilayer, and multilayer circuit board is divided into inner layer and outer layer. For example, mobile phones, computer motherboards, etc., require multi-layer circuit boards to reduce the size. The inner layer circuit is in the middle of the circuit board, so the inner layer circuit does not require appearance, but emphasizes function.
所以,內層線路的微蝕強調盡量使表面粗內糙,當進行壓合的時候使兩層線路板粘合性較好。一般的微蝕使用過硫酸鈉,不僅能清潔粗化線路銅面,還能確保圖形電鍍銅與一次銅之間的結合力。
Therefore, the micro etching of the inner layer circuit emphasizes to make the surface as rough as possible, so that the adhesion of the two layers of circuit boards is better when pressing. Generally, sodium persulfate is used for micro etching, which can not only clean the copper surface of roughened circuit, but also ensure the adhesion between pattern electroplating copper and primary copper.
使用過硫酸鈉進行微蝕的話粗化速率較為穩定均勻,水洗性好,是其它物料所不能比擬的。
When sodium persulfate is used for micro etching, the roughening rate is more stable and uniform, and the water washing property is better than that of other materials.

過硫酸鈉在PCB生產中作為微蝕劑使用時也沒有明顯不同,因此給一些商人有機可乘,以過硫酸銨冒充過硫酸鈉的個案在珠三角地區并不鮮見,在珠三角周邊地區更為嚴重。
The use of sodium persulfate as a micro etchant in PCB production is not obviously different, so some businessmen have the opportunity to take advantage of the fact that the case of passing off ammonium persulfate as sodium persulfate is not uncommon in the Pearl River Delta region, especially in the surrounding areas.
假冒的過硫酸鈉不僅對電路板企業的廢水處理帶來困擾(氨氮容易超標),也帶來了儲存的危險性(按過硫酸鈉的條件儲存過硫酸銨有可能釀成火災),還給我們生產過硫酸鈉的企業帶來經濟上的損失,過硫酸鈉被假貨冒充導致價格長期偏低。
The counterfeit sodium persulfate not only brings troubles to the wastewater treatment of circuit board enterprises (ammonia nitrogen is easy to exceed the standard), but also brings risks to the storage (storing ammonium persulfate under the conditions of sodium persulfate may lead to a fire). It also brings economic losses to our enterprises producing sodium persulfate. The price of sodium persulfate is low for a long time because it is counterfeited.
因此,對于過硫酸鈉的選購您要多提起精神來查看驗收,不要一味的被低廉價格所懵逼。更多相關內容就來我們網站http://www.mybuildingdesignz.com留言咨詢吧!
Therefore, for the purchase of sodium persulfate, you should pay more attention to check the acceptance, and not be fooled by the low price. More relevant content will come to our website http://www.mybuildingdesignz.com Leave a message for consultation!
