Technical Problem
通过外协定制探针卡，定制周期需要3~5工作日，准备周期长，费用高，灵活性差；使用普通探针卡加转接外延板卡手工制板，但外延板卡因测试距离偏长引起线容性干扰大，还会存在使用外延板卡错误的可能，导致样品测试损坏等质量问题，无法进行电容或小量程项目测试，也无法将调试用探针卡直接转量产
Benefits of technology
[0015]所述转接板设有飞线连接区与元件增补区，所述飞线连接区设有飞线焊盘，用于外接飞线；所述元件增补区设有元件焊盘，用于元件增补安装。飞线连接区和元件增补区能够实现快速外接线路或增补元件，适配不同测试需求；可通过飞线和元件扩展功能无需重新制作转接板，降低开发成本。与现有技术相比，本实用新型的有益效果是：基板设计为通用底板，配备可拆卸转接板适配不同样品测试，不需定制高精度探针卡；转接板采用防呆接口设计，防止误接导致电路异常；连续环形焊接区形成完整的接地回路，有效抑制信号串扰和电磁干扰；通过等长弯曲上下层布线降低线阻和感性容性干扰；转接板支持飞线和元件扩展，满足外围电路测试需求，显著降低测试成本与周期；同时缩小试验调试用的探针卡与量产探针卡的数据误差，使试验用探针卡趋向于量产探针卡结构，节约成本。
