How to determine the quality of OKI soldering iron tips?

How to determine the quality of an OKI soldering iron tip? As a well-known distributor of OKI soldering iron tips in Shenzhen, Shenzhen Yapude Technology Co., Ltd. can evaluate the quality based on the following points.

1. Size and accuracy do not necessarily need to be as high as possible, attention should be paid to several key dimensions, installation dimensions, and head dimensions;

2. Appearance, regardless of the color of the shape, whether it is black, bright, or white, the color of the surface electroplating of the soldering iron tip has two main purposes: rust prevention and anti leakage tin. Regardless of the color, the outermost surface must be chromium, which only prevents tin from crawling;

3. Pinholes, the iron head should be carefully examined. If there are no pinholes, then this iron head is definitely not a good thing;

4. Inner hole, the soldering iron tip has an inner hole, and the inner surface should be as smooth as possible;

5. Destruction, this is the highest level of measurement method. Open the head contusion file and see that the base must be made of purple copper and the iron layer must be thick, but not too thick. A thickness of 0.8 ≤ 1.1mm can be considered as the top grade;

6. Lead free, if it is a lead-free iron head, the tin in front of the head cannot look very good because pure tin has weak fluidity and a slightly black appearance. If the head is too bright and beautiful, it may be lead-free.

The above points are all used to determine the quality of OKI soldering iron tips, and can also be used to determine the practicality of the product based on its size, shape, pinholes, inner holes, degree of damage, and whether it contains lead.
