Step S1: when the chip carrier plate stays in the preheating box and the retest cooling box of each temperature zone and reaches the process temperature, judging whether a transmission mechanism of the whole calibration line is in an idle state, and whether the test boxes of each temperature zone and the retest cooling box of the retest zone complete the calibration test and transfer the corresponding next process position; if so, go to step S2; otherwise, waiting for the transmission mechanism of the whole calibration line to be in an idle state, completing the calibration test of the test box of each temperature area and the retest box of the retest area, and transferring the chip carrier plate to the corresponding next process position.
Because 23 process positions (excluding a loading unit and an unloading unit) are arranged in the sensor chip calibration line equipment, each chip carrier plate must sequentially pass through each process position, and in order to avoid temperature leakage between different temperature zones as much as possible, only two to five adjacent chip carrier plates are allowed to simultaneously move between at most two boxes with different temperatures, so that at least three process positions are free and used as buffer positions for chip carrier plate transfer according to the layout of each test temperature zone and each box. Meanwhile, a certain chip carrier needs to stay at a certain process position for a certain time to adjust the temperature of the chip carrier, and the chip carrier cannot be moved in the period, so that other chip carriers cannot be moved when the chip carrier stays, and therefore, all chip carrier transfer actions of the whole line must be coordinated to be performed in a uniform takt time. When a chip carrier plate of a test box in a certain temperature area is tested, the corresponding buffer box is always in an idle state; and when the test is finished, transferring the chip carrier plates to the corresponding buffer boxes, waiting for the whole line to be in an idle state, and waiting for starting the chip carrier plate transfer of each process position by taking the state at the moment as an initial state.
And judging whether the chip carrier plate of the buffer box of a certain temperature zone directly enters the preheating zone of the next temperature zone or the chip carrier plate of the cooling box of the re-measurement zone directly enters the re-measurement box, and whether the conditions of dewing, expansion due to heat, contraction due to cold and the like caused by temperature difference damage the hardware structure of the chip carrier plate or the equipment. If so, transferring the chip carrier plate of the temperature zone buffer box to a corresponding transition box, enabling the chip carrier plate to stay in the transition box for one beat period, stably recovering the temperature to the normal temperature, and transferring the chip carrier plate to a preheating box of the next temperature zone in the next beat period; and transferring the chip carrier plate of the cooling box in the retest area to a writing box, enabling the chip carrier plate to stay in the writing box for one beat period, stably recovering the temperature to the normal temperature, and transferring the chip carrier plate to the retest box in the next beat period.
In this step, it is determined whether the temperature of the chip carrier in the temperature zone buffer box reaches the allowable temperature threshold of the next temperature zone preheating box. If the temperature reaches the admission temperature threshold value, transferring the chip to a corresponding transition box, and after the chip is temporarily stopped, transferring a process position to the downstream side together with the chip carrier plate of the preheating box of the next temperature zone; a chip carrier plate at the outlet of the preheating box of the next temperature zone enters a corresponding test box, a chip carrier plate of a transition box of the temperature zone and three chip carrier plates in the inlet direction of the preheating box of the next temperature zone together enter four process positions of the preheating box; in this case, the chip carrier directly enters the temperature environment of the next temperature zone from the temperature environment of the current temperature zone. If the allowable temperature threshold value is not reached, transferring four chip carrier plates in the preheating box of the next temperature zone to a process position in the downstream direction, namely, transferring one chip carrier plate at the outlet of the preheating box into a corresponding test box, and transferring one process position of three chip carrier plates in the inlet direction of the preheating box to the outlet direction, and then transferring the chip carrier plate of the buffer box of the temperature zone to the transition box of the temperature zone so as to enable the chip carrier plate to stay in the transition box for one beat period; under the condition, after leaving the temperature area, the chip carrier plate is firstly stably restored to the normal temperature in the transition box, and then enters the temperature environment of the next temperature area.
In this step, it is also determined whether the temperature of the chip carrier in the review area cooling box reaches the access temperature threshold of the review box. If the access temperature threshold is reached, transferring the data to a writing box, and transferring the data to a retesting box after short stay; in this case, the temperature of the chip carrier is reduced from the high temperature only after the time of one cycle of the temperature reduction box from the high temperature region. If the admission temperature threshold value is not reached, transferring the data to a writing box, and enabling the data to stay in the writing box for one beat period; in this case, the temperature of the chip carrier is lowered from a high temperature to a normal temperature after leaving the high temperature zone and in the cooling box and the writing box for a total of two clock cycles.
By the scheduling method for the calibration test of the chip carrier plate, the calibration operation of four chips can be simultaneously carried out, namely the four test temperature areas on the calibration line simultaneously calibrate the chips on the four chip carrier plates, so that the production efficiency of the calibration line is improved, and the redundancy of the number of the chip carrier plates of the whole line is reduced. In addition, the embodiment of the application can also ensure that when the chip carrier finishes the test of a certain temperature zone and enters the next temperature zone, the phenomenon that the chip and a hardware mechanism are damaged due to condensation or expansion with heat and contraction with cold caused by overlarge temperature difference between the chip carrier and the next temperature zone is avoided.
