FIG. 1 shows a flowchart of a method for burning chips in batch according to the present invention.

As shown in fig. 2, a plurality of independent chips 11 are arranged on the PCB 1, each chip 11 is provided with a burning point 111 and a metal terminal 112, the burning point 111 is mainly used for burning programs, and the metal terminal 112 is mainly used for electrically connecting with a terminal device, so that the terminal device performs data interaction with the chip through the metal terminal. The terminal equipment can be a mobile phone, a computer, a PAD and the like. But is not limited thereto.
As shown in fig. 3, the burning apparatus 2 includes a burner (not shown), a controller (not shown), a floating mechanism (not shown), and a plurality of burning pins 21. The burner can be electrically connected with the plurality of burning needles 21, the corresponding burning needles 21 are contacted with the burning points of the chip, and the burner burns programs to the chip by means of the corresponding burning needles. The controller is used for controlling the floating mechanism, and the floating mechanism acts on the plurality of burning needles. It can be understood that the number of the burning needles is larger than that of the burning points on the PCB, when the PCB moves to the burning device, only part of the burning needles can be aligned to the burning points on the PCB, and other burning needles are not aligned to the burning points on the PCB and are idle. The controller controls the floating mechanism to descend the burning needle at the burning point, and the burning needle is accurately contacted with the corresponding burning point. Compared with the traditional manual operation mode, the automatic chip burning method has the advantages that the full-automatic chip burning process is realized, the accuracy of butt joint of the burning needle and the burning point is improved, and the yield of chip burning is further improved.
It can be understood that, for a chip manufacturer, in order to improve the productivity of the chip, a server is used to coordinate a plurality of burning devices to complete the program burning operation of the chip, the server includes a program library, a plurality of programs are stored in the program library, and each burning device is in communication connection with the server and is used to receive the burning task distributed by the server and to realize the batch burning operation of the chip according to the burning task.

Meanwhile, the limited and proper target burning devices are screened out, and the burning tasks of the same batch are intensively distributed to the target burning devices, so that the burning tasks of the same batch are not distributed to all the burning devices, and the collection, packaging and other operations of finished products of the chips of the same batch at the later stage are facilitated.
It should be noted that the server of the present invention can be communicatively connected to the customer order system, and can formulate and distribute the burning task based on the batch orders of the customers, so that the number of chips finally burned accurately matches the customer demand, and the problems of prolonged construction period, increased cost, waste of redundant chip resources, etc. caused by the mismatch between the number of chips burned and the customer demand are avoided.
According to an embodiment of the present invention, after the selected recording device with the last preset bit is taken as the target recording device, the method further includes:

It should be noted that, the recording devices and the detecting devices are grouped in pairs, that is, one detecting device is corresponding to the back of each recording device, when a task is formulated and allocated, a recording task is allocated to a target recording device, and a detecting task is also allocated to a target detecting device behind the target recording device, after the target detecting device receives the allocated detecting task, the detecting task is placed in a buffer queue, until the sequence of the detecting task is updated to the forefront of the buffer queue, the program detecting work of the chip recording of the batch is executed.

electrifying each chip on the PCB by the target detection device;
respectively inputting detection instructions to each chip, wherein the detection instructions can output corresponding target detection results by the operation of the detection program;
the burned programs of all chips are operated based on the detection instruction;
acquiring actual detection results output by each chip, and judging whether the actual detection results are the same as the target detection results; if the program detection of the target chip is qualified, and if the program detection of the target chip is not qualified, the program detection of the target chip is unqualified.
According to the embodiment of the invention, when the corresponding target burning device finishes the burning of the chips in a certain batch, the preset time period is interrupted and the burning of the chips in the next batch is executed, and the preset time period is more than or equal to the time from the burning end to the detection start of the chips.
It should be noted that the detection can be performed only after the chip burning is completed. When the target burning device finishes the chip burning of the last PCB of a certain batch, the chip of the last PCB cannot be timely transmitted to the subsequent target detection device under the limitation of transmission delay, at the moment, if the previous target burning device starts to execute the chip burning of the next batch without interruption, the chip burning of the next batch may be confused with the chip of the previous batch, and the target detection device fails to detect the chip of the next batch because the chip detection program of the previous batch is different from the chip detection program of the next batch, and the chip of the two batches is confused after the chip of the two batches is confused.

and after the signature verification is successful, decrypting the ciphertext by using the shared secret key to obtain the burning task.
It should be noted that, since the burning device needs to complete batch burning of chips according to the burning task, once the burning task has an error or is tampered by a third party, the problem that the burning of the large batch of chips is not qualified is caused. After the server works out the burning task, the burning task can be encrypted by adopting a shared key between the server and the burning device, so that the burning task is transmitted by a ciphertext, and other people are prevented from stealing the burning task. Meanwhile, the server also adopts the private key of the server to sign the ciphertext, and after the burning device receives the signature information, the signature verification can be carried out on the signature information through the public key of the server, so that the phenomenon that other people illegally falsify the burning task by the server is effectively prevented, and the confidentiality and the safety of data transmission between the server and the burning device are further enhanced.

receiving the signature information by a corresponding target detection device, and checking the signature through a public key;
and after the signature verification is successful, decrypting the ciphertext by using the shared secret key to obtain the detection task.
It can be understood that the invention effectively enhances the confidentiality and the security of data transmission between the server and the detection device by adding security mechanisms such as encryption, decryption, signature and the like between the server and the detection device.
According to the embodiment of the invention, the order number and the burning number are integral multiples of the number of chips carried by a single PCB.
Furthermore, the detection number is also an integral multiple of the number of chips carried by a single PCB.
It can be understood that because the burning device uniformly burns all the chips on the one-to-one whole PCB at the same time, in order to avoid the waste of the residual chips caused by the fact that the last batch of chips of the burning task does not meet the chip quantity of the whole PCB, the invention carries out the specified requirement on the order quantity of the customer when receiving the order of the customer, and leads the order quantity to be the integral multiple of the chip quantity carried by a single PCB, thereby being convenient for burning and detecting the chips of the whole PCB in the follow-up process.

according to the order quantity of the batch orders and a corresponding distribution algorithm, corresponding burning tasks are formulated and distributed to the target burning devices, and the distribution quantity of each target burning device is as follows: (c-a)1),(c-a2),…,(c-an)；
Wherein n is the number of target recording devices, a1,a2,…,anThe current task quantity of the n target burning devices is obtained; c is the average value estimated by each target recording device after distribution, and
