'<br>The use of hot water is present at every step of the PCB production. This is also true in the final testing and inspection operations. It is essential for the device to pass all the tests set by quality control personnel and quality inspection teams. This is especially true for the final test of resistivity, moisture resistance and dielectric properties. A difference in the water used in PCB manufacturing process and testing can affect the test results dramatically.<br><br><br>Typically, the hot water is pumped during the first few stages of the pcb manufacturing process. This is done to soften the copper wafers during the bending process. The use of water with higher temperature can help reduce distortion and increase the reliability of the circuit boards during the test and inspection operation. However, it is not always advisable to use the higher temperatures because they have some disadvantages like increased rejection and more production losses.<br><br><br>One of the most common methods of testing the resistance of the pcb is the thermal conductivity test. This process is normally performed using a special instrument called a thermal conductivity meter. This instrument can measure the temperature of the water that is used in the process and determine the conductivity of the material. This is often used to determine the amount of heat resistance that is present.<br><br><br>Another method of testing the hot water is the electrical discharge testing. During this process, the electric current that is used to charge the wafers is measured and compared with the electric voltage that is present. If the results are significantly different, then it is an indication that the temperature of the water used in the process is different from the normal level. Hence, the electrical conductivity of the material must be different for the hot water to match the required temperature in the pcb manufacturing process.<br><br><br>In addition to the above-mentioned tests, there are many other procedures that can be used to test the water used in the process. For instance, the oxygen transfer process can be used to check whether the presence of contaminants is present in the heated water. Different techniques such as electromagnetic absorption can also be used to check whether the water is capable of passing through various layers of the pcb. The rate at which the water flows is another important factor that is tested during the testing process.

This is because the rate at which the hot water is consumed is also important.<br><br><br>It is necessary to note that in any of the above-mentioned processes, the temperature of the heated water should be greater than the freezing point of water. In order to achieve this, several steps are required. First, the required amount of heating is carried out. Once the desired temperature is achieved, the water is brought to room temperature and the procedure is repeated.<br>'
