First, compare the parameters first
Usually each furnace temperature tester will list the characteristics of its products. Of course, the accuracy of these parameters cannot be fully trusted, but they can be used as a reference for preliminary selection, such as sampling frequency. The fastest
is seconds, which is definitely better than seconds. Lithium battery charging is definitely better than nickel-metal hydride battery. Communication is definitely better than lithium battery. Large memory (number of sampling points) is definitely better than small memory. . .
Second, physical size
The physical size mainly refers to the width of the oven temperature tester. If the width of the oven temperature tester itself is too wide, it will be narrower than the oven temperature tester and difficult to place in the reflow chamber. In the furnace track, it is very inconvenient.
Usually the appropriate width (insulation box) is between. It should be as narrow as possible.
Third, lead-free process
The main consideration for the lead-free process of the furnace temperature tester is the insulation effect of the thermal insulation box. Usually, the temperature requirements of the lead-free process are higher than those of the ordinary process. Will this temperature cause the internal operation of the furnace temperature tester to be unstable? Causes sampling temperature to be inaccurate? On the other hand, if the lead-free process is used, the ordinary process will be the same.
Fourth, on-site testing
Before purchasing, you must conduct on-site testing. Only on-site testing can find problems
Stability of the instrument
The same reflow oven can be tested repeatedly. Let's make a comparison and you can see the problem.
, Accuracy of the instrument
Different trigger temperatures and different sampling frequencies can be set for testing and comparison.
, The ease of use and completeness of software operation (especially for new companies, it is recommended to choose the simpler the operation, the better)
The operating software of a well-known brand is nested layer by layer, confusing people. In the fog. Because the software is not structured and modular.
Without solder paste library and equipment library, process analysis would be impossible. This is a big flaw.
, after-sales service (it is better to have a longer warranty, the faster the maintenance cycle, the better, and of course the more technical support points, the better.)
I recommend purchasing more advanced furnace temperature testers from some domestic professional furnace temperature tester manufacturers. For the right fit, Shenzhen Jingkechuang Electronic Equipment Co., Ltd. will be your best choice.
