In the SMT assembly line, reflow machine is an essential equipment. Reflow machine temperature is very critical, so the production line will be reflow soldering temperature profile measurement, then measure the reflow oven need to pay attention to those aspects?
1. The test board with the memory device into the furnace, pay attention to the memory device from the test PCB board distance in 100mm or more, so as to avoid heat interference.
2. Reflow machine furnace in the boot half an hour to achieve thermal equilibrium of the furnace, so the requirement to open the furnace at least half an hour of operation before the temperature profile of the test and production.
3. The temperature curve printed out in accordance with the preheating temperature time, reflow machine peak temperature, reflow time and the rate of temperature rise and fall of the comprehensive consideration of adjusting the equipment to meet the requirements of the temperature curve, due to the different thermal capacity of the test points and characterize the performance of the reflow furnace temperature inhomogeneity factors, the temperature curve of the three test points will be a certain difference.
4. The temperature curve of the record: in addition to the printout of the temperature curve, to show the range of the parameters required and the actual value, the set value of the equipment, the distribution of the test point location and the direction of the test board into the determination of the time and the results of the judgment.
5. Frequency of measurement: In principle, once a week, but also in accordance with customer requirements when individual customer requirements are implemented, in the setup changes, product changes, depending on the need to carry out the temperature curve test.
