检查测试探针的四个技巧（中英文）

以下提示将帮助检查弹簧测试探针并确保可靠的接触：

测试探针的使用寿命取决于其应用和条件。探针的使用寿命取决于弹簧力、是否遵守建议的工作行程、侧向力的存在、电流负载以及污染和热量等外部影响等参数。定期检查可避免不必要的停机并优化使用寿命。

The following tips will help you to check spring-loaded test probes and guarantee reliable contacting:

The service life of test probes depends on their application and condition. The service life of probe depends on parameters such as spring force, adherence to the recommended working stroke, the presence of side forces, current load, as well as external influences such as contamination and heat. Regular checks prevent unnecessary downtime and optimise the service life.

1. 柱塞磨损。

Wear on the plunger.

机械磨损会缩短探针的使用寿命。插入测试点的深度越深，弹簧力越大，磨损就越严重。侧向载荷和挠度会增加镀层的磨损，也会缩短测试探针的使用寿命。

Mechanical wear reduces the service life of the probes. The deeper the penetration depth into the test point and the higher the spring force, the higher the wear. Side loads and deflection increase the wear of the plating layers and also reduces the service life of the test probes.

2. 定期清洁测试探针。

 Clean test probes regularly.  

清洁垫可用于清洁指针柱塞尖端。所有其他尖端样式都用刷子或油漆刷清洁以去除残留物。焊料残留物和助焊剂等污染物会粘附在柱塞尖端上，并可能导致电阻增加或伪错误。用刷子清洁时应格外小心。清洁过程中单个引脚上的侧向负载可能会导致柱塞永久变形。不应使用带有金属刷毛的刷子。合适的接触式清洁垫在此很有用。将其切割成 DUT 的尺寸并放置在测试夹具中而不是 DUT 中。关闭测试夹具时，测试探针会刺穿清洁垫。接触式清洁垫的特殊成分可产生清洁效果。对于顽固污染，可重复该过程几次。

Cleaning mats can be used to clean pointer plunger tips. All other tip styles are cleaned with a brush or paintbrush to remove residue. Contamination such as solder residues and flux stick to the plunger tip and can cause increased resistance or pseudo errors. Extreme care should be taken when cleaning with a brush. Side loads on individual pins during cleaning can cause permanent deformation of the plunger. Brushes with metal bristles should not be used. An appropriate contact cleaning mat is helpful here. This is cut to the size of the DUT and placed in the test fixture instead of the DUT. When closing the test fixture, the test probes pierce the cleaning mat. The specialised composition of the contact cleaning mat creates the cleaning effect. For stubborn contamination, the process can be repeated several times.

3.符合机械和电气数据

Compliance with the mechanical and electrical data

符合机械和电气数据以及工作温度范围。只有这样，弹簧式测试探针才能保证可靠的接触和较长的使用寿命。

Compliance with the mechanical and electrical data as well the operating temperature ranges. Only then can the spring-loaded test probes guarantee reliable contacting and a long service life.

4.使用合适的插入和提取工具。

 Use suitable insertion and extraction tools.

只有使用最佳安装的插座和测试探针，才能保证可靠的测试。

Only with optimally installed receptacles and test probes, can reliable testing be guaranteed.
