Embodiment 1

[0034] Example 1 : PCB golden finger insertion force test

[0035] The test sample is a PCB gold finger with a planar structure, and the gold plating thickness is ≥0.30 μm. A total of 2 groups were tested, that is, the control group 1# without lubrication treatment and the test group 2# after lubricating treatment with the water-soluble electrical contact lubricant protection agent provided by the present invention.

[0036] 1#: Blank control group without lubrication treatment.

[0037] 2#: Use the water-soluble electrical contact lubricant protection agent of the present invention for lubrication treatment. The thickness of the film layer is 10~20 nm (5~10 molecular layers).

[0038] The ratio (by weight percentage) of the water-soluble electrical contact lubricant protection agent concentrate used in this embodiment is as follows:

[0039] Stearyl alcohol (stearyl alcohol) 4.5% and cyclohexyl hexaphosphate (phytic acid) 5.5% (molar ratio=2:1);

Embodiment 2

[0051] Example 2 : Effects of fatty alcohols with different numbers of C atoms on the lubricating properties of electronic components.

[0052] This example investigates the effect of fatty alcohols with different C atom numbers on the lubricating properties of electronic components. Used test sample, test method are exactly the same as embodiment 1. Except for fatty alcohol and phytic acid, the water-soluble electrical contact lubricant protection agent concentrate used in this embodiment, the remaining components and their weight percentages are exactly the same as in Example 1

[0053] The total weight percentage of fatty alcohol and phytic acid is still 10%, and the molar ratio of the two is about 2:1. The weight percentage composition of the two is shown in Table 2.

Embodiment 3

[0059] Example 3 : the influence of the mol ratio of fatty alcohol and phytic acid on the lubricating performance of the present invention.

[0060] When the fatty alcohol has 12-18 carbon atoms, it will work with phytic acid, and the influence on the lubricating performance of the present invention is mainly related to the molar ratio of the two. This example investigates the influence of different molar ratios of fatty alcohol and phytic acid on the lubricating performance of the present invention.

[0061] In this embodiment and all subsequent embodiments, stearyl alcohol is selected as the fatty alcohol used in this patent. The test samples and test methods used in this embodiment are exactly the same as those in Example 1; except for stearyl alcohol and phytic acid, the water-soluble electrical contact lubricant protection agent concentrate used has the same components and their weight percentages as in Example 1. .

[0062] In this embodiment, the total weight percen...

Abstract

The invention discloses a water-soluble electric contact lubricating protective agent improving the pluggable resistance of an electronic element and a use method thereof. The water-soluble electric contact lubricating protective agent comprises the following components in parts by weight: 10-15 parts of fatty alcohol and inositol phosphate, 3-6 parts of natural phospholipid, 3-8 parts of corrosion inhibitor, 10-20 parts of composite surfactant system, 15-25 parts of chelating agent, and 10-20 parts of detergent. A protective agent is adopted to lubricate the electronic element, and the protective agent is firstly diluted by 10-100 times with pure water, and preferably 100/8-100/4. Soaking technology is adopted for lubrication, the temperature is 20-60 DEG C, the time is 30-90 seconds, the drying temperature of a workpiece subjected to lubrication is 80-150 DEG C, and the time is 30-120 seconds. After the electronic element is treated by the protective agent disclosed by the invention, through a pluggable force test, an abrasion test and a salt fog test, the results show that the friction of the electronic element is obviously reduced, the pluggable resistance is obviously enhanced, and the long-term reliability of products is obviously improved.

Description

Technical field [0001] The invention belongs to the field of electronic component surface treatment technology, especially involving a water -soluble electrical contact lubricant and its related processing processes to improve the resistance of electronic components. Background technique [0002] In recent years, with the rapid development of electronic technology and the succession of the high -tech electronics industry, the market competition of electronic products has become increasingly fierce.Electronic products must be continuously promoted, towards the trend of high -quality, portable and multi -functional combinations.As the most basic unit of electronic products, the quality of its performance directly determines the quality of electronic products.If electronic components lack excellent plug -in resistance, it will have a very serious impact on electronic products.Due to the poor resistance of electronic components, the electronic products formed by the assembly are repe...
