In the era of mobile phone electronics consumer market, there is one performance that manufacturers have been working hard to overcome, and that is the waterproof test of mobile phone SIM card trays.When manufacturing the mobile phone SIM card tray, whether the mobile phone SIM card tray can be tested for waterproofing is another upgrade in the waterproof testing technology of the mobile phone SIM card tray.In today's waterproof testing market, what we know is that the military and three-proof aircraft industries have always maintained a good habit of waterproof testing.However, we rarely see this type of mobile phone on the market at present. This is also a pain point for rugged mobile phones. The reason is that its bulkiness and appearance cannot be accepted by consumer groups.However, after Samsung and Apple successively launched waterproof mobile phones in the consumer market, this market had a great impact, because it can not only ensure the convenience and beauty of the mobile phone, but also ensure that the mobile phone will not have any impact even if it is soaked in water, so that consumer groups can play with their mobile phones while taking a bath like Japanese girls.And when it comes to the waterproof testing principle of mobile phone card trays, it is estimated that many people are thinking about this issue.
If our smartphones need to be tested for waterproofing, then there are many problems that need to be solved, such as the mobile phone sim card holder, charging port, headphone port, mobile phone front case LCD, mobile phone side buttons, mobile phone card holder, mobile phone HOME button and mobile phone back antenna, etc. We must do waterproof protection.Regarding the waterproof testing of these components, today Shenzhen Hirays used the waterproof test of mobile phone SIM card trays to explain to the industry how the mobile phone SIM card trays are waterproofed.
