The Chroma 1870D Series (1870D/1870D-12) are specifically designed automated test equipment for chip inductors. It comprises various test functions that are required for verifying chip inductors. In addition, an automated tape packaging machine at the end of production line is equipped to fulfill demand for automated manufacturing.
Chroma 1870D系列的标准测试功能是电感（LS）/质量因子（Q），绕组电阻（RDC）测量和极性测试，以及可选层短（IWT），绝缘电阻（IR）和偏置电流测试，这些测试覆盖所有用于测量芯片电感器质量和标准规格的测试项目。
由于当今的电子产品广泛使用微型电感器，因此需要大量的芯片电感器产生。亚博app下载网址Chroma 1870D/1870D-12的生产能力高达1200 ppm，可以满足所需数量。除了测试外，1870D/1870D-12还配备了自动包装机，并机械地将电感器打包，以满足SMD生产线的所需样式。
Chroma 1870D/1870D-12使用一个圆形振动板，该振动板以高速饲喂薄产品。亚博app下载网址圆形振动板使用导轨设计，纤维检测和吹孔来确定进料方向。与传统的线性往复机械馈线相比，这是快速和节省的。
When moving inductors for testing, the traditional reciprocating or turret-type mechanical structure uses a nozzle to attract the inductor for movement, and the product often drops due to inertial effects or inaccurate positioning making it unable to test. The Chroma 1870D/1870D-12 uses an index disc design for testing, so that the equipment is within a closed architecture that can eliminate dropped inductors during highspeed movement. It is faster and more stable when compared to the traditional mechanical structure.
Chroma Ate Inc。not only specializes in electronic testing technology but are also masters in fixture design for automated test equipment. The test socket used by the Chroma 1870D/1870D-12 test station is a four-wire measurement design that is more accurate and stable than common automatic test equipment. The chip design applied to the connection of the test socket and inductor is easier to contact and has longer product life compared to a probe in use. The chip design is also more stable and easier to maintain than a probe.
Chroma 1870D/1870D-12具有独家软件，可实时监测测试状态，并为每个电感器保存收集的测试数据。实时监控功能可以通过降低制造过程中的生产风险并减少不必要的工作时间来使生产单元受益。数据收集功能有利于R＆D和QA单元用于产品分析和质量控制。
Applications
Batch verification for RD and QA
由于需要研发和质量检查单元检查所有产品的功能是否具有基本的电气特性和质量相关测试，极性测试的测试数据，层短测试（或偏置电流测试）亚博app下载网址，绕组电阻测试和电感/质量因子测试站收集和分析数据以进行质量评估或生产用于步道生产的样品。Chroma 1870D/1870D-12测试和包装机提供了灵活的选择，以适合不同单元所需的测试站。
Fully Functional Electrical Characteristics
生产线测试
All electrical characteristics are adapted into the production line based on the R&D unit to comprise polarity test, layer short test (or bias current test), winding resistance test and inductance/quality factor test.
生产线的标称价值快速测试
For production line, only test nominal value is required for fast production. The test items applied are winding resistance test and inductance/quality factor test.
System Reserved Space for Marking
and Optical Inspection of Marks
Certain power inductors require marking on the top to identify the polarity and inductor type. The Chroma 1870D/1870D-12 can integrate the marking and optical inspection systems owned by customer into the system.
