What is the nature of reflow welding in PCB manufacturers?  

What is the nature of reflow welding in PCB manufacturers?   The essence of reflow welding is “heating”, the core of the process is to design the temperature curve and set the furnace temperature.   The temperature curve refers to the “temperature-time” curve developed by the technician based on the representative package and solder paste of …

What is SMT Surface Mount Technology?

Tag: PCBA assembly Surface Mount Technology (SMT), also known as Surface Mount Technology, is a new generation of electronic assembly technology. It compresses traditional electronic components into components with only a few tenths of the volume, thereby realizing high-density, high-density electronic product assembly. High reliability, miniaturization, low cost and automation of production. The process method …

Analysis of the reasons for the pickup failure in the 01005 component smt patch

Analysis of the reasons for the pickup failure in the 01005 component smt patch? Recently, a customer asked during a pre-consultation: I have to post relatively few materials, each board has two kinds of materials, 01005 capacitors, 0201 magnetic beads, because 01005 capacitors have a narrow tape, 4x4mm SIZE, 0.4mm thick The width of the …

How to choose the surface treatment process of the circuit board?

How to choose the surface treatment process of the circuit board? After we design the PCB board, we need to choose the surface treatment process of the circuit board. The commonly used surface treatment processes of the circuit board are HASL (surface tin spraying process), ENIG (immersion gold process), OSP (anti-oxidation process), and the commonly …

What are the certifications of PCBA processing factories?

What are the certifications of PCBA processing factories? Many PCBA processing factories pay great attention to the quality management system, and generally apply for many quality certification certificates for the factory. The investment of this certification fee is more importantly concerned with the degree of trust the customer has in the PCBA processing plant. The …

What should be paid attention to when welding double-sided circuit boards?

What should be paid attention to when welding double-sided circuit boards? Double-sided circuit board In order to ensure the reliable conductive effect of the double-sided circuit, the EDA365 Electronics Forum recommends that the connection holes on the double-sided board (that is, the through-hole part of the metallization process) should be soldered with wires or the …
