【摘要】：隨著科技日新月異地發(fā)展,用于各種電子電器設(shè)備起電氣連接作用的印制線路板,也隨之被要求更復(fù)雜更精密的線路設(shè)計(jì)。隨著印制線路板的線路設(shè)計(jì)更復(fù)雜越精準(zhǔn),導(dǎo)致原本一直被行業(yè)忽略的漲縮問(wèn)題也被越來(lái)越多客戶提上日程要求印制線路板制造商進(jìn)行管控。長(zhǎng)期處于印制線路板制造行業(yè)技術(shù)和質(zhì)量領(lǐng)跑者的A公司,面對(duì)眾多客戶突然提出的對(duì)于印制線路板漲縮管控的要求,雖然有著行業(yè)最領(lǐng)先的設(shè)備,最領(lǐng)先的技術(shù)和經(jīng)驗(yàn)豐富的工程師。但對(duì)于影響因素復(fù)雜,影響制程跨度大的漲縮問(wèn)題卻無(wú)法進(jìn)行良好的控制,且要在滿足客戶要求的同時(shí),又讓自己企業(yè)的成本降到最低。六西格瑪管理是現(xiàn)行最有效的質(zhì)量管理方法。在六西格瑪六大主題的指引下,運(yùn)用六西格瑪特有的“DMAIC”步驟,從剖析客戶的需求出發(fā),分析現(xiàn)有A公司漲縮問(wèn)題的現(xiàn)狀,以及和客戶需求的差距。尋找公司內(nèi)部影響漲縮的因子,指定改善方案。并加入精益生產(chǎn)的理念,剔除非增值活動(dòng),規(guī)范步驟,簡(jiǎn)化步驟,并引入防呆防錯(cuò)理念,控制并維護(hù)改善的效果。六西格瑪項(xiàng)目小組,在集合各部門各工序的工程師,從“零”開(kāi)始重新研究A公司漲縮的現(xiàn)狀、多次運(yùn)用頭腦風(fēng)暴和魚(yú)骨頭系統(tǒng)的查找可能的影響因素。層層把關(guān),收集數(shù)據(jù),縮小有影響的工序的范圍。對(duì)最終經(jīng)過(guò)分析判定為有影響的工序,進(jìn)行再一次的數(shù)據(jù)收集,實(shí)驗(yàn)安排和實(shí)驗(yàn)結(jié)果驗(yàn)證,在不影響其他印制線路板重要特性的前提下,制定最佳制程參數(shù)和最佳流程。在原有模糊地憑“經(jīng)驗(yàn)”制定的漲縮控制流程上,改善參數(shù),重新制定規(guī)則,改善流程。并對(duì)有關(guān)聯(lián)的工程系統(tǒng)也采取改善行動(dòng),避免任何的由手動(dòng)操作帶來(lái)的錯(cuò)誤,導(dǎo)致大批量產(chǎn)品的報(bào)廢。同時(shí),根據(jù)A公司現(xiàn)有的各生產(chǎn)系統(tǒng),工程系統(tǒng)和監(jiān)控系統(tǒng),開(kāi)發(fā)一套獨(dú)有的自動(dòng)漲縮系統(tǒng)。該自動(dòng)漲縮系統(tǒng)不單具有警告功能,還有反饋預(yù)警功能和自動(dòng)計(jì)算并建議補(bǔ)償值功能。該系統(tǒng)不單彌補(bǔ)了操作員可能會(huì)漏放漲縮超規(guī)范的產(chǎn)品流入下工序,當(dāng)產(chǎn)品漲縮的趨勢(shì)有所不對(duì),還能及時(shí)得發(fā)預(yù)警給相關(guān)工程師,同時(shí)還會(huì)經(jīng)過(guò)后臺(tái)的計(jì)算,建議具體的修改值。且在后臺(tái)進(jìn)行計(jì)算之前,系統(tǒng)還會(huì)自動(dòng)檢查該批次的相關(guān)生產(chǎn)信息和工程信息,自動(dòng)過(guò)濾非計(jì)算范圍內(nèi)的產(chǎn)品數(shù)據(jù)。大大降低了工程師面對(duì)龐大的、多個(gè)數(shù)據(jù)庫(kù)的信息處理時(shí)的工作量,提高了效率又提高了準(zhǔn)確性。對(duì)于部分特殊產(chǎn)品,雖然還未能用自動(dòng)漲縮系統(tǒng)進(jìn)行控制,但為了避免不合格品流入客戶手中,也加入了適當(dāng)?shù)谋O(jiān)控方法和全面的預(yù)防漲縮超規(guī)范的流程。并在監(jiān)控方法中加入自動(dòng)化元素,及時(shí)有效的監(jiān)控漲縮,以最大限度達(dá)到客戶滿意。
[Abstract]:With the rapid development of science and technology, printed circuit boards (PCB), which are used for electrical connection of various electronic and electrical equipment, are also required to be more complex and more precise circuit design. As the circuit design of printed circuit board becomes more and more complex and accurate, the rising and shrinking problem, which has been ignored by the industry, has been put on the agenda of more and more customers to control printed circuit board manufacturers. Company A, which has long been a technology and quality leader in the printed circuit board manufacturing industry, is facing the sudden demands of many customers for the control of the rise and shrink of printed circuit boards, although it has the industry's leading equipment. The most advanced technical and experienced engineers. However, it is difficult to control the increase and shrink of the large span of the manufacturing process because of the complexity of the influencing factors, and it is necessary to meet the requirements of the customers, and at the same time, the cost of the enterprise can be reduced to the lowest. Six Sigma management is the most effective quality management method. Under the guidance of six major themes of six Sigma, using the "DMAIC" step of six Sigma, starting from the analysis of customers' needs, this paper analyzes the current situation of current A Company's rising and shrinking problems, and the gap between the existing A Company and customer needs by using the six Sigma-specific "six Sigma" steps. Look for the factors that affect the increase and contraction of the company, and specify the improvement plan. Adding the idea of lean production, eliminating the non-value-added activities, standardizing the steps, simplifying the steps, and introducing the idea of preventing blunders and preventing errors, controlling and maintaining the effect of improvement. The six Sigma project team, which brings together engineers from various departments and processes, has revisited the current situation of Company A's rise and contraction from "zero" and has repeatedly used brainstorming and fish bone system search for possible influencing factors. Layer by layer check, collect data, narrow the scope of the affected process. The data collection, experiment arrangement and experimental results are carried out again for the process which is finally determined to be affected by analysis. The optimal process parameters and flow chart are worked out without affecting the important characteristics of other printed circuit board (PCB), and the optimal process parameters and flow chart are worked out without affecting the important characteristics of the other printed circuit board (PCB). Improve the parameters, re-establish the rules, and improve the process of the increase and shrink control process, which is based on the previous "experience" vaguely. The associated engineering systems are also improved to avoid any errors caused by manual operation, resulting in the scrapping of large quantities of products. At the same time, according to the existing production system, engineering system and monitoring system of A Company, a unique system of automatic increase and shrink is developed. The automatic rise-shrink system not only has warning function, but also feedback early warning function and automatic calculation and recommended compensation function. The system not only makes up for the fact that the operator may omit the overstandard product flow into the next process, when the trend of the product rises and shrinks is wrong, it can also get early warning to the relevant engineers in time, and at the same time, it will also go through the backstage calculation. Suggest specific changes to the value. And before the backstage calculation, the system will automatically check the relevant production and engineering information of the batch, and automatically filter the non-calculated product data. It greatly reduces the workload of engineers when dealing with large, multi-database information, and improves the efficiency and accuracy. For some special products, although the automatic increase and shrink system has not been used to control them, in order to avoid the non-conforming products coming into the hands of customers, a proper monitoring method and an all-round process of preventing inflation and shrinkage overspecification have also been added. The automation element is added to the monitoring method to monitor the rise and fall in time and effectively, in order to reach the satisfaction of the customers as much as possible.
