Rapid Change Temperature Test for 5G Optical Module, Optical Fiber Communication Parts

In order to facilitate the assembly line workers less complicated to execute product testing, Wewon Environmental Chambers Co., Ltd. has created a brand-new type rapid temperature change test chamber for high quality inspection and product research study. The rapid temperature change test chamber mostly made use of for optical communication component, semiconductor chip’s reliability and performance test solutions. Gloveboxes environmental chamber is fitted with a huge sight window and unique glove ports for accessibility to the test area. The diameter of glovebox iris port is 100 mm.

With the glove box sleeves, the employee who deal with production line can check the top quality of the checked samples online during the test, This method will certainly not affect its temperature and humidity variations. Long time low temperature procedure, the test room without any frost also the machine runs for a very long time. An LED light is mounted on the top of the sight window to plainly observe the example discovery scenario in the test room.

The Wewon’s rapid temperature change test chamber is equipped with two 1.5 kW French Tecumseh compressors, Cooling capability temperature change rate can be 3 ℃/ minutes. The equipment can carry out internet product high quality inspection task according to the defined temperature change rate. The quantity and wind rate will certainly be changed automatically, This makes the temperature in the test area is evenly distributed. Through a digital expansion valve, The surface temperature distinction of the checked product is suppressed, and the linear control accuracy is recognized.

Rapid Temperature Change Test Chamber For Quality Inspection And Product Research

Rapid temperature change test chambers prominent used for 5G optical component, optical fiber communication parts. The failing risk of various products can be tested only under radical temperature modifications. For +85 ℃ and -40 ℃ temperature test, It has to remain long sufficient for the tool to get to ambient temperature. rapid temperature changes also trigger greater anxiety on the evaluated product. When the tons is even more than 100 Kg, Linear 15 ℃/ min, with tons in the heating and cooling down procedure, Test room’s temperature variance within ± 2.0 ℃.

Rapid Temp Change Test Chamber’s Usage: The equipment is mainly made use of for the metal products of electronic items and their versatility test and tension screening test under the simulated environment condition of rapid change or progressive change of temperature, Test and judge the physical and various other relevant homes of the product. There no need to close the door or open, the checked sample can be placed in or gotten openly with the procedure opening.

Rapid temperature change testing chambers from Wewon Environmental Chambers Co., Ltd. pick the touch screen control method to record the temperature (humidity) contour in real-time procedure of the experiment, which can be remotely controlled and managed via the computer system software. test requirement for glovebox iris port temperature cycle test chamber comply with GB/T2423.22, IEC 60068-2-14, JESD 22-A104-D, JESD 22-A105-C.

The heating and cooling rate is at least 10℃/min, and the cycle test is performed at the two temperature points of 85℃ and -40℃

Wewon’s environmental chamber with glove ports can be utilized very long time online with low-temperature operation without defrosting in the test room. It is considerably enhance the performance of production test (The normal environmental chambers need to be heated up and defrosted, and after that lined up to cool down, which is power-consuming and certainly time-consuming).

Wewon’s environmental glove chamber with huge and intense monitoring window with broad visual field: adopts three-layer vacuum coating window and energy-saving fluorescent light, does not need wipers to defog, preserves a clear monitoring impact in the gloveboxes environmental chamber, and can observe the problem of the sample in the quickly temperature change test chamber at any time.
