PCB 电测试--测试点数自动输出到流程指示中(读取TGZ Stephdr文件)

Posted 2020-12-25 pcbren

正好这里有一项需求：PCB电测试--测试点数自动输出到流程指示中

 

一.自动输出测试点小结;

    1.由于历史原因；各工厂差异,测试点数统计单位差异，有的工厂为PCS计算测试点，有些工厂一年前是按PCS计算测试点，而最新测试点是以PNL计算；

        而流程指示中统一为PNL为测试点单位统计，在制作前，要识别此坑，不要往里面跳了。

    2.另一个，有些客户来的CAM资料是Set为单位，工程CAM制作时是不会再拆为PCS作业，而之前的规则是以PCS计算测试点的，而此测试点数是以SET计算测试点，

       而转为PNL测试点时，无法准确测试点数的单位到底是SET还是PCS,可能导致转为PNL测试点错误。

    3.基于以上2点问题，解决方法是：读取TGZ  Stephdr拼板及工程标准命名规范识别PNL中拼了多少个SET,多少个PCS。计算出转换值。

 

二.读取TGZ  Stephdr文件

Stephdr  Mod类

    public class STEP_REPEAT
    {
        public string NAME { get; set; }
        public double X { get; set; }
        public double Y { get; set; }
        public double DX { get; set; }
        public double DY { get; set; }
        public int NX { get; set; }

        public bool MIRROR { get; set; }
        public List<STEP_REPEAT> STEP_REPEAT_List { get; set; }
    }

 

三.读取 ZIP 测试点文件

        private void readTestPoint()
        {
            int resultCount = 0;
            string tarFilePath = @"\\192.168.224.8P2Dc2018dc-test400000004a00n0nb.zip";
            string FileName = Path.GetFileNameWithoutExtension(tarFilePath);
            using (Stream stream = File.OpenRead(tarFilePath))
            {
                IReader reader = ReaderFactory.Open(stream);
                while (reader.MoveToNextEntry())
                {
                    if (reader.Entry.Key.EndsWith("profile.cmb"))
                    {
                        using (EntryStream st = reader.OpenEntryStream())
                        {
                            byte[] byData = new byte[reader.Entry.Size];
                            st.Read(byData, 0, byData.Length);
                            string result = System.Text.Encoding.Default.GetString(byData);
                            resultCount = int.Parse(result);
                            break;
                        }
                    }
                }
            }
        }
