How to choose PCBA processing solder paste: (1) according to the value and use of pcb circuit board products,(2) according to the storage time of PCB and components and surface oxidation degree determines the activity of solder paste. (3) Select solder pa
In the production process, it can be prevented in the following ways: 1, moisture-proof storage of components, 2, select good quality solder paste, 3, adjust printing parameters of false welding and false welding problems, 4, control the welding time, 5,
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.
PCBA welding processing, usually PCB board has a lot of requirements, and must meet the requirements of the board to accept welding processing.
At this stage, we move from written blueprints to physical representations constructed using laminate or ceramic materials. Some of the more complex applications require flexible PCBS when particularly compact Spaces are required.
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.
Next, I will introduce the research and development process of PCBA products.1. Market research; 2. Prototype and interaction design; 3. Hardware development - main chip confirmation
The basic working conditions of PCBA patch after processing are as follows: 1. Working conditions: Temperature: 18℃ to 28℃, humidity: 35% ~ 75%; 2. 2. Operation object: all PCbas; 3. Operator: with certain general SMT and DIP welding status identification
As an important part of PCBA, SMT processing has a direct impact on product quality. SMT processing includes multiple processes. How to standardize each process so as to post perfect PCBA
How to improve the SMT patch processing quality?First, select technical personnel, second, ensure the accuracy of equipment, third, set up quality detection control points, fourth, improve the management system, five, formulate rules and regulations
Some basic testing and inspection tasks may be required to be performed on your PCB/PCBA during the manufacturing and assembly process, and it is recommended that these tests be performed, at the very least, to ensure continuity, accurate assembly, and si
Quality control in mass production and prototyping has a common set of important tasks: the need for PCB testing. The specific set of tests you need to perform in a PCBA depends on its application area, desired service conditions, and, of course, the rele
