近几年,电子产品朝轻,薄,短,小化迅速发展,印制线路板也随着这股潮流朝向高密度封装方向发展。尤其是积层板总数的增加和导通孔以及连接盘的小径化也日益显著。对于积层线路板而言,用来加工层间连接的盲通孔(BVH)的激光方法取决于导通孔和连接盘径。激光器分为CO2激光和UV-Yag激光两种。导通孔径为60μm以上时,则一般用CO2激光加工。由于铜在CO2激光的波长(9.3μm～10.3μm)领域中的吸收比很低,因此"保形法"(在表面铜箔上,蚀刻出需要的加工孔径(开铜窗),再以激光打掉树脂)成为了现在的主流。然而,由于保形法需要蚀刻开铜窗,因此增加了形成图形的工序,而且导通孔的定位取决于下层的定位标记,容易发生错位。随着积层板层数的增加,导通孔和连接盘的小径化发展,越来越需要提高加工速度和定位精度。因此,同时对铜和树脂进行加工的"直接钻孔法"开始被关注。直接钻孔法是根据格柏数据进行导通孔的定位,因此,即使导通孔/连接盘径越趋小型化,也不会发生错位,是一种能够推进多层化,高密度化的先端技术。本文讲述了以直接钻孔法形成高可靠度导通孔时所需的技术和药品。

AIM: To investigate changes over time in, and effects of sealing technology on, milk test results following pancreatectomy. METHODS: From April 2008 to October 2013, 66 pancreatic resections were performed at the Iwakuni Clinical Center. The milk test has been routinely conducted at the institute whenever possible during pancreatectomy. The milk test comprises the following procedure: A nasogastric tube is inserted until the third portion of the duodenum, followed by injection of 100 mL of milk through the tube. If a chyle leak is present, the patient tests positive in this milk test based on the observation of a white milky discharge. Positive milk test rates, leakage sites, and chylous ascites incidence were examined. Liga Sure?(LS; Covidien, Dublin, Ireland), a vessel-sealing device, is routinely used in pancreatectomy. Positive milk test rates before and after use of LS, as well as drain discharge volume at the 2^(nd) and 3^(rd) postoperative days, were compared retrospectively. Finally, positive milk test rates and chylous ascites incidence were compared with the results of a previous ***: Fifty-nine milk tests were conducted during pancreatectomy. The positive milk test rate for all pancreatectomy cases was 13.6%(8 of 59 cases). One case developed postoperative chylous ascites(2.1% among the pancreatoduedenectomy cases and 1.7% among all pancreatectomies). Positive rates by procedure were 12.8% for pancreatoduodenectomy and 22.2% for distal pancreatectomy. Positive rates by disease were 17.9% for pancreatic and 5.9% for biliary diseases. When comparing results from before and after use of LS, positive milk test rates in pancreatoduodenectomy were 13.0% before and 12.5% after, while those in distal pancreatectomy were 33.3% and 0%. Drainage volume tended to decrease when LS was used on the 3^(rd) postoperative day(volumes were 424 ± 303 mL before LS and 285 ± 185 mL after, P = 0.056). Both chylous ascites incidence and positive milk test rates decrea

目的研究吞咽过程中舌压传感器的应用是否对屈曲传感器所记录的喉部运动波形产生影响.方法选取12名健康成年男性为受试者,嘱所有受试者端坐位吞咽5 m1水,比较同一受试者在同时贴附属曲传感器和舌压传感器以及仅贴附属曲传感器而不贴附舌压传感器两种情况下吞咽屈曲传感器的记录参数.结果统计显示,无论贴附舌压传感器与否,屈曲传感器所记录吞咽过程中喉部运动波形的同一标志时间点彼此之间的差异均无统计学意义（P＞0.05）,而且屈曲传感器记录的喉部运动各时期持续时间也不因贴附舌压传感器而发生变化（P＞0.05）.结论吞咽时舌压传感器的贴附不影响屈曲传感器记录的喉部运动,为将来同步应用舌压传感器和屈曲传感器测定吞咽过程中舌压生成与喉部舌骨运动生理协同性研究提供了基础.

AIM: To evaluate our experience and surgical technique of laparoscopic appendectomy via reduced port surgery(LARPS). METHODS: Sixteen patients(8 men and 8 women; median age: 31.0 years) who underwent LARPS between November 2009 and May 2012 were included in the present study. We performed LARPS, in which access devices were inserted through an umbilical skin incision with 1 additional skin incision in the left lower abdomen. After setting access devices, pneumoperitoneum was maintained at 10 mmH g using CO2 and a 3 mm trocar was positioned(or direct puncture was performed by the Endo Relief system) under laparoscopic guidance. The mesoappendix was dissected using an ultrasonically activated device. After mesoappendix dissection, ligation was performed near the appendix base and the appendix was dissected using an ultrasonically activated device. The appendix was then removed. At the end of surgery, we administered local anesthesia with ropivacaine 1%(10 mL) for the skin incisions. The outcomes were evaluated in terms of operation time, intraoperative blood loss, length of postoperative hospital stay and surgical complications. RESULTS: Our surgical procedure allowed operators to use instruments as in conventional laparoscopic appendectomy. The basic principle of triangulation of instrumentation was maintained to some degree. LARPS was performed in 9 patients with catarrhal appendicitis, 5 with phlegmonous appendicitis, and 2 with gangrenous appendicitis. The median surgery time was 60 min and the median intraoperative blood loss was 1.2 mL. The median length of postoperative hospitalization was 4 d. There were no conversions to open surgery, no operation-related complications or mortality. CONCLUSION: Our experience and surgical technique suggest that LARPS is a safe and feasible procedure for patients with appendicitis.
