The measurement method is to dissolve the sample in hot alcohol with titanium phenol as an indicator, titration required potassium hydroxide milligram number, namely its acid value.
When the infrared frontal temperature gun is aimed at and close to the distance between the measured object and the tube measured by the sensor, the infrared sensor plate will collect the temperature and convert it into an electrical signal.
In the choice of PCBA patch processing manufacturers, electronics factories are very careful, so we should choose from the following points: first, customer experience, second, production qualifications, three, cost, four, service
There are six points to evaluate the manufacturability of PCB design:1. DFM review of light board2. Check the consistency between the actual components and the pad3. Generate 3D graphics: heat, whether it is conducive to SMT reflow welding heat absorption
The processing of plug-in components generally adopts wave soldering. Because the wave soldering time is very short, if the jack is connected to more ground/electric layers, the tin penetration will be poor, resulting in poor welding.
How to achieve high PCB spread rate and shorten the design time, which is a lot of people are considering the problem, this time, long Bo technology and you discuss the design skills of pcb board layout.
Therefore, pcb manufacturers believe that when designing or reinforcing equipment, they should be placed on PCB boards with higher hardness, or use certain methods to avoid pcba processing.
Take you to PCB processing and SMT patches as well as subsequent testing and inspection to have a comprehensive understanding of first, tin slag recycling problems, second, material loss rate
