的價格 印刷電路板 是許多買家一直困惑的事情. 許多人還想知道在網上下訂單時這些價格是如何計算的. 讓我們來談談 印刷電路板 一起定價.
1. 影響價格的各種因素 印刷電路板板
1. 使用的不同資料 印刷電路板導致價格差异
For example, 普通雙面板, the sheet 材料 generally has FR4 (Shengyi, 主控板, 郭籍, three prices from top to bottom), 厚度為0.2毫米至3.0毫米, 銅的厚度從0.5盎司至3盎司. 所有這些都造成了板材的巨大價格差异; 就阻焊油墨而言, 普通熱固性油和光敏綠油之間也有一定的價格差异.
2. 不同的 印刷電路板表面 treatment processes cause price diversity
Common ones are: OSP (anti-oxidation), 鉛噴錫, lead-free tin spray (environmental protection), 鍍金, 浸沒金, 和一些組合過程, 等. 上述過程的價格隨著時間的推移而變得更加昂貴.
3. 價格差异造成的困難 印刷電路板本身
Two kinds of 印刷電路板板 have 1000 holes. 一塊板的孔徑大於0.2mm,另一塊板孔徑小於0.2mm, 這將導致不同的鑽井成本. 所有類型都大於4mil, 一種小於4mil, 這也會導致不同的生產成本; 其次, 一些不遵循普通電路板流程的設計也是額外的資金, 例如半孔, 埋置盲孔, 磁片上的孔, 和按鈕板印刷碳素油.
4. The different thickness of copper foil causes price diversity
Common copper and platinum thicknesses are: 18um (1/2OZ), 35um (1OZ), 70um (2OZ), 105um (3OZ), 140um (4OZ), 等. 隨著時間的推移,上述銅箔的厚度變得更加昂貴.
5. Customer's quality acceptance criteria
Commonly used are: IPC2, IPC3, 企業標準, 軍用標準, 等. 標準越高, 價格越高.
6. Mold fee and test stand
(1) Mold cost. 對於樣品和小批量, 通用板廠採用鑽銑成型, 並且沒有額外的研磨費用. 大量生產時, 需要沖模, 所以有一組模具成本. 板廠報價一般在1元以上,000.
(2) Test fee: The prototype is generally tested by flying probes, 而板廠一般收取100-400元的測試費; 必須打開測試架進行批量測試, 而通用板製造商的報價介於1,000-1,500元.
7. The price difference caused by different payment methods
The shorter the payment time, 如現金支付, 價格越低.
8. 訂單數量/Delivery Time
(1) The smaller the quantity, 價格越貴, 因為即使是1件, 板廠必須做工程數據, 電影已經上映了, whichever process is indispensable
(2) Delivery time: The data delivered to the 印刷電路板工廠 must be complete (GERBER information, 電路板的層數, 板的厚度, 如何處理表面處理, 墨水的顏色, the color of the characters and some special requirements must be clearly written)
From the above discussion, 不難看出 印刷電路板加工價格 has its inherent inevitable factors. 本文只能提供一個粗略的價格範圍供參考. 當然, 具體價格仍與廠家直接聯系.
2. Quotation of various factors
For 印刷電路板, we have a set of valuation formulas (that is, the utilization rate of the board). 具體如下:基於1平方米的板, its size is 1020mm*1020mm, 假設 印刷電路板 待評估為L,寬度為H. 1平方米的基板可以生產這種電路板, the quantity is (1020/L+5)*(1020/H+5)=Z (that is, the typesetting quantity) Unit price=X/Z, X是以下價格.
