To ensure service quality, we will check all SMT processing and DIP welding processes :1. PCB factory inspection,2. High temperature baking before production,3. 3D AOI solder paste printing inspection,4. Optimal cost accounting,5. Technical feasibility st
Test methods that can be used to identify counterfeit electronic parts in routine operations: first, visual inspection, second, electrical testing, third, X-ray inspection, fourth, XRF technology
When PCBA is processed in the furnace: Because the pin of the plug-in element is scour by tin flow, some plug-in elements will be tilted after welding in the furnace, resulting in the element body beyond the screen frame, so it is required to repair weldi
General items to be checked after PCB wiring include: General PCB design drawing check items, PCB physical characteristics, PCB installation requirements, PCB electrical characteristics, PCB mechanical design factors, PCB removal requirements, PCB electri
FPCS have many applications in a number of different fields. They are used in solar cells, mobile phones, vehicles and aircraft. Many of these applications require thin and durable flexible sheets, which can therefore withstand bending, folding or rolling
Printed circuit boards consist of electrically conductive tracks that interconnect components on the board. They are also commonly used for electrical safety testing or verification
Common causes of material loss in SMT patch processing: 1, human factors, 2, machine factors, 3, material reasons, 4, working methods, 5, production environment
The main reasons for solder joint failure in PCBA processing are as follows: 1, component pin is bad: 2, PCB solder pad is bad: 3, solder quality defects: 4, solder quality defects: 5, process parameter control defects: 6, other auxiliary materials defect
Methods for rapid maintenance of faults after PCBA processing: one, visual inspection method, two, resistance method, three, voltage method, four, waveform method, five, current method, six, component replacement method, seven, step by step investigation
When the solder paste reaches the melting temperature, under the action of balanced surface tension, there will be a self-positioning effect, that is, when there is a small deviation from the component placement position, under the action of surface tensi
Why do PCBA circuit board inspection: PCBA inspection is a link in the whole production process of PCBA processing, is an important means to control product quality
Classification of PCBA inspection items: inspection items are divided into four categories: material inspection, process inspection, identification inspection and quality consistency inspection
