Description
本發明係有關於一種以鑽針分析鑽孔品質的方法及系統，尤指一種能夠分析使用過的鑽針的鑽刃狀態，再以鑽刃狀態對照所鑽的孔的品質及孔位精度。The present invention relates to a method and system for analyzing drilling quality with a drill needle, and in particular, a method and system that can analyze the drill edge state of a used drill needle, and then compare the drill edge state with the quality and hole position accuracy of the drilled hole.
印刷電路板是電子、電腦及通信等產品之主要零組件，為能因應消費市場上輕、薄、短、小之產品特性，及在高密度及高可靠性的需求催化下，除了通孔之精密鑽孔需要外，高階印刷電路板在目前的發展趨勢更多使用盲孔(blind hole或via)及埋孔(buried hole)之鑽孔技術。該種盲孔及埋孔之印刷電路板，是藉由盲孔將內部幾層之佈線板與表面之佈線連接，不須穿透整個板子而浪費其他層佈線板之佈局空間，預估可較一般印刷電路板之體積縮小20%。因此對電路板而言，無論是半成品或成品，盲孔或通孔之品質檢測工作都變的非常重要，特別是關於線寬、孔徑、孔垂直度、孔真圓度及銅墊尺寸等都需要進行量測及規格判讀。Printed circuit boards are the main components of electronics, computers and communications products. In order to cope with the characteristics of light, thin, short and small products in the consumer market, and catalyzed by the demand for high density and high reliability, in addition to through-hole In addition to the need for precision drilling, the current development trend of high-end printed circuit boards is to use blind hole (via) and buried hole (buried hole) drilling technologies. This kind of blind via and buried via printed circuit boards use blind vias to connect several internal layers of wiring boards to the wiring on the surface. There is no need to penetrate the entire board and waste the layout space of other layers of wiring boards. It is estimated that it can be longer Generally, the size of printed circuit boards is reduced by 20%. Therefore, for circuit boards, whether they are semi-finished products or finished products, quality inspection of blind holes or through holes has become very important, especially regarding line width, aperture, hole verticality, hole roundness and copper pad size, etc. Measurement and specification interpretation are required.
目前自動光學檢測(automatic optical inspection)機係分別量測各片印刷電路板上鑽孔精度，並單獨以數據或圖表呈現各片印刷電路板之鑽孔精度的量測結果。然同樣規格印刷電路板之鑽孔品質常會因著不同鑽孔機或製造時間而變異，也就是會因著鑽孔機之設定、廠牌或使用狀態而造成鑽孔品質變異，或者是相同鑽孔機也會因著製造時間而產生鑽孔品質之變異，例如：刀具磨損或定期保養之時間等。Currently, automatic optical inspection machines measure the drilling accuracy of each printed circuit board separately, and present the measurement results of the drilling accuracy of each printed circuit board individually in data or charts. However, the drilling quality of printed circuit boards with the same specifications often varies due to different drilling machines or manufacturing time. That is, the drilling quality will vary due to the settings, brand, or usage status of the drilling machine, or the same drilling machine will not produce the same drilling quality. Drilling machines will also produce variations in drilling quality due to manufacturing time, such as tool wear or regular maintenance time.
很明顯現有自動光學檢測機並無法有效呈現或提示品質變異之趨勢，往往是等到印刷電路板之量測結果發現異常或不符規格，才開始提停止生產問題貨批及追查問題發生根源，因此會造成生產中斷及無法有效預測品質異常之可能發生的問題。It is obvious that existing automatic optical inspection machines cannot effectively present or indicate the trend of quality variation. They often wait until the measurement results of printed circuit boards find abnormalities or do not meet specifications before they start to stop the production of problematic batches and trace the root cause of the problem. Therefore, it will Possible problems that may cause production interruptions and inability to effectively predict quality abnormalities.

為便於說明本發明之內容及所能達成之功效，茲配合圖式列舉具體實施例，請參照第一圖，本發明一種利用鑽針的耗損判斷鑽孔品質之方法，其步驟包含：In order to facilitate the explanation of the content and achievable effects of the present invention, specific embodiments are listed in conjunction with the drawings. Please refer to the first figure. The present invention is a method for judging the quality of drilling by using the wear of drill needles. The steps include:
1.對至少一鑽針安裝一無線辨識元件。1. Install a wireless identification element on at least one drill bit.
2.該鑽針分別對複數板體進行鑽孔，當該鑽針的鑽孔次數達到一第一預定次數及一第二預定次數時分別停止使用該鑽針。2. The drill needle drills holes on a plurality of boards respectively, and stops using the drill needle when the number of drilling holes by the drill needle reaches a first predetermined number of times and a second predetermined number of times.
利用該鑽針上的無線辨識元件，能夠確認以該鑽針進行鑽孔的各該板體、孔位及次數，藉此達到追蹤效果。The wireless identification element on the drill needle can be used to confirm the plate body, hole position and number of holes drilled with the drill needle, thereby achieving tracking effect.
請參照第二圖及第三圖，3.利用一光學設備對該鑽針拍攝一第一相片10及一第二相片20，該第一相片10係為該鑽針的鑽孔次數達到該第一預定次數時的鑽刃11平面圖，該第二相片20係為該鑽針的鑽孔次數達到該第二預定次數時的鑽刃21平面圖。Please refer to the second and third figures. 3. Use an optical device to take a
請參照第二圖至第四圖，4.以一分析裝置接收該第一相片10及該第二相片20，並分析對該第一相片10及該第二相片20中的鑽刃11、21，計算該鑽刃11、21的損耗面積，其演算法為100%-(該第一預定次數的鑽刃面積111/新鑽針的鑽刃面積311)%=第一損耗面積；100%-(該第二預定次數的鑽刃面積211/新鑽針的鑽刃面積311)%=第二損耗面積。Please refer to the second to fourth figures. 4. Use an analysis device to receive the
除了利用上述演算法之外，也能夠以圖形化比對分析損耗面積，請參照第四圖，為預先儲存在該分析裝置的第三相片30，該第三相片30為新鑽針的鑽刃平面圖，以該新鑽針的鑽刃面積311，比對該第一相片10及該第二相片20中的鑽刃面積111、211，即能以目視觀察到該第一相片10及該第二相片20中的鑽刃面積111、211相比新鑽針的鑽刃面積311縮小量及變形量。In addition to using the above algorithm, the loss area can also be analyzed graphically. Please refer to the fourth figure, which is a
5.分別檢驗該第一預定次數前及該第一預定次數後至該第二預定次數前的板體的孔洞的孔位精度及孔壁品質，並比對該第一損耗面積與該第一預定次數時的孔洞的孔位精度及孔壁品質，及該第二損耗面積與該第二預定次數時的孔洞的孔位精度及孔壁品質，當該鑽針的第一損耗面積或該第二損耗面積大於或等於70%時，則判定該鑽針為不合格，且該第一預定次數的孔洞的孔位精度及孔壁品質或該第二預定次數的孔洞的孔位精度及孔壁品質則越差。5. Check the hole position accuracy and hole wall quality of the holes in the plate body before the first predetermined number of times and after the first predetermined number of times and before the second predetermined number of times, and compare the first loss area with the first predetermined number of times. The hole position accuracy and hole wall quality of the hole at the predetermined number of times, and the second loss area and the hole position accuracy and hole wall quality of the hole at the second predetermined number of times, when the first loss area of the drill needle or the third When the second loss area is greater than or equal to 70%, the drill bit is determined to be unqualified, and the hole position accuracy and hole wall quality of the first predetermined number of holes or the hole position accuracy and hole wall quality of the second predetermined number of holes are The quality is worse.
6.儲存該第一損耗面積、該第二損耗面積、該第一預定次數的孔洞的孔位精度及孔壁品質及該第二預定次數的孔洞的孔位精度及孔壁品質的比對結果。6. Store the comparison results of the first loss area, the second loss area, the hole position accuracy and hole wall quality of the first predetermined number of holes, and the hole position accuracy and hole wall quality of the second predetermined number of holes. .
以該第一損耗面積及該第二損耗面積分別對應該第一預定次數及該第二預定次數時的鑽孔品質及孔位精度，隨著實務操作，會逐漸累積形成龐大的資料庫，因此能夠更細膩、精準的判讀損耗面積值的大、小與孔位精度及孔壁品質的關聯性。The first loss area and the second loss area respectively correspond to the drilling quality and hole position accuracy at the first predetermined number of times and the second predetermined number of times. With practical operations, a huge database will be gradually accumulated and formed. Therefore, It can more delicately and accurately judge the correlation between the large and small loss area value, hole position accuracy and hole wall quality.
更詳細而言，損耗面積大於或等於70%時，則判定該鑽針為不合格，需要淘汰或研磨該鑽針，然而並非指所有損耗面積70%以下的鑽孔品質與孔位精度都符合要求，因此在實務上為了取得最佳的孔位精度及孔壁品質，則需要隨時調整該第一預定次數及該第二預定次數，藉此達成不同品質與精度要求的客戶群。In more detail, when the loss area is greater than or equal to 70%, the drill bit is judged to be unqualified and needs to be eliminated or ground. However, this does not mean that the quality and hole position accuracy of all drilling holes with a loss area of less than 70% meet the requirements. Therefore, in practice, in order to obtain the best hole position accuracy and hole wall quality, it is necessary to adjust the first predetermined number of times and the second predetermined number of times at any time, so as to meet customer groups with different quality and accuracy requirements.
換言之，當客戶群設定了更高標準的鑽孔品質與孔位精度時，則要降低損耗面積值，例如從70%改為50%，由於損耗面積值降低，也需要同時降低鑽針的第一預定次數與第二預定次數，以利於掌握鑽刃狀態。In other words, when the customer base sets higher standards for drilling quality and hole position accuracy, the loss area value must be reduced, for example, from 70% to 50%. Due to the reduction in the loss area value, the drill bit also needs to be reduced at the same time. A predetermined number of times and a second predetermined number of times to facilitate grasping the state of the drill blade.
