How to improve reliability of PCB equipments

Technical Library | 2012-12-12 03:17:51.0

When we designed the PCB equipments, we should try to simplify crcuit and structure design that on the premise of ensuring the equipments to meet the technology and performance, In modern society, modules design (MD)is a effective measures to improved the pcb equipment reliability. The system were made up simpleness functions of modules to reducing the complexity of the design. Both domestic and abroad, a large number of facts have proved this point, MD was a best choice for PCB equipment design.

How to Control Speed of Servo Motor & Anti-Interference Measures

Technical Library | 2021-12-31 01:27:08.0

A servomotor refers to the actuator to control the operation of mechanical components in the servo system and is a subsidy motor indirect transmission device. The servo motor can control speed, whose position accuracy is high, and convert voltage signal into torque and speed to drive the controlled object. A servomotor speed is controlled by the input signal, responding quickly.

An Engineer's Guide to Testing and Evaluating The Performance of Desiccant Bags for the Protection of Critical Moisture Sensitive Devices

Technical Library | 2020-08-16 14:50:25.0

Not all desiccant bags are created or perform equally. Performance measures include: a) How long does desiccant last? b) How much are can be desiccated in a given area? c) How much moisture is retained, and or released back into the atmosphere? This article walks engineers through various test they can perform to determine efficacy. Additionally, the article highlight between adsorption vs adsorption.

How to inspect the temperature recovering time of thermal shock chamber?

Technical Library | 2019-11-12 02:09:22.0

Thermal shock test chamber can be used for testing the chemical change or physical damage on composite materials caused by the thermal expansion and contraction of the sample in the shortest time,which is subjected to extremely and continuous high and low temperature environment.so how to check the temperature recovery time of this chamber? Normally we take following steps to inspect the temepratuire recovering time: 1.Install the temperature sensor at the specified position, and adjust the temperature controller of hot zone and cold zone to the required nominal temperature respectively. 2.The temperature increases and reduces respectively,30min after temperature in two zones reach stable status,record temperature value of the measuring point,pls set the temperature value of two zones to be required nominal temperature. 3.The temperature shock test chamber automatically places the inspected load into theh ot zone,select the corresponding retention time according to regulated standard. 4.Set the transfer time,then the inspection load is transferred from hot zone to cold zone, and the temperature of the measuring point is observed and recorded, and then the reverse conversion of the load from cold zone to hot zone is carried out according to the same method, and the temperature of the measuring point is observed and recorded. www.climatechambers.com
