Problems solved by technology

But the disadvantage of this solution is that the cost is too high, and because the physical and chemical properties of different plastics are quite different, the requirements for molding molds and temperatures will be different, so it is necessary to redesign certification, change mold fixtures and other equipment, so that lead to a sharp increase in costs

Abstract

The invention discloses an electronic component, which can protect the part of the insulator exposed below the circuit board from being damaged in a high-temperature welding environment, and has lower cost. The electronic component includes an insulator and a number of conductors accommodated in the insulator, and at least a part of the insulator is exposed under the circuit board after being assembled on the circuit, and it is characterized in that the part of the insulator exposed under the circuit board is properly treated , so that the part can withstand higher temperature. Compared with the prior art, the electronic component of the present invention properly handles the part of the insulator exposed below the circuit board, so that this part can withstand a higher temperature, thereby not only achieving the purpose of protecting the part from damage, but also The cost is lower.

Description

【Technical field】 [0001] The invention relates to an electronic component, in particular to an electronic component used to protect its plastic feet from being damaged in lead-free soldering. 【Background technique】 [0002] General electronic components, such as electrical connectors, are composed of conductors and insulators. Most of the conductors are metal parts, and most of the insulators are plastic parts. When assembling it with the circuit board, soldering techniques are generally used. However, in the soldering process, currently used solders contain lead. Lead is an element harmful to humans and the environment. With the enhancement of people's awareness of environmental protection, the requirements for the impact of chemical components contained in various electronic products on the human body are becoming more and more stringent, and lead-free manufacturing processes have become the current trend. Compared with adding metallic lead to the solder in the past, th...
