The factory for assembling electronic products mainly includes two production lines: SMT surface assembly and DIP plug-in assembly. SMT is the process of attaching electronic components onto a PCB circuit board through a device, then heating them in a furnace (usually referred to as a reflow soldering furnace), and fixing the components onto the PCB board […]

During SMT processing, electrostatic discharge can cause damage or failure to electronic components. With the improvement of IC integration and the gradual reduction of components, the impact of electrostatic discharge becomes increasingly severe. According to statistics, static electricity accounts for 8% to 33% of the factors that lead to the failure of electronic products, and […]

What is Impedance Control and Signal Matching Impedance control is matching PCB trace dimensions and locations with the properties of the substrate material to make sure that the strength of a signal traveling along a trace is within a required range. The continual increase in device switching speeds is confronting engineers with signal integrity(SI) problems and eventually, most devices are going to have to deal with SI issues. So, Printed […]

PCB boards are usually composed of multiple layers stacked together, with each layer performing a different function. The following are common PCB layers and their meanings: Signal layer: The signal layer is one of the most important layers on the PCB board. It contains the signal transmission path between electronic components and realizes signal transmission […]

1.Incoming Inspection Incoming inspection refers to the confirmation and verification of the quality of purchased raw materials, components, or products, that is, the quality is inspected through sampling when the supplier sends the raw materials or components, and the final judgment is made whether the batch of products is accepted or rejected. 2.Meaning IQC is […]

¿Qué es el apilamiento de PCB? En circunstancias normales, cuando se diseñan placas ordinarias de una o dos caras, no es necesario tener en cuenta el problema de laminación de la placa de circuito impreso. Normalmente, se selecciona directamente una placa revestida de cobre con un grosor de cobre y un grosor de placa que cumplan los requisitos de diseño para su procesamiento directo. Sin embargo, cuando se diseña una PCB con [...]

Una vez finalizada la prueba de parches SMT de la fábrica de procesamiento de pequeños lotes de parches SMT, se requieren algunos procedimientos de procesamiento de seguimiento, como pruebas, montaje, etc. Una vez completados todos los eslabones del procesamiento electrónico, se entrega al cliente. Es relativamente fácil ser perturbado por diversos factores en la entrega y el transporte [...]

Cada fabricante de montaje de PCB debe adherirse a las normas de limpieza adecuadas. Ahora la aparición de la placa de circuito requisitos de limpieza son cada vez más estrictas, sin afectar el trabajo de la Junta, nuestra fábrica de DYC ha estado trabajando duro para entregar una placa de circuito limpio a cada cliente。 1.Comply con IPC-5704 Todo el desarrollo de dispositivos médicos [...]
