Abstract

The invention relates to the field of electrically erasable programmable read-only memory (EEPROM), and especially relates to an EEPROM on-line burner and an on-line burning method. The method comprises the following steps: mounting a blank IC on a PCBA by SMT mounting; inserting a master IC into an IC seat of the burner, connecting the obtained PCBA to the burner, burning the data information of the master IC onto the blank IC of the PCBA by the burner; comparing the data of the master IC with the data of the IC of the PCBA by the burner, reading the data of the IC of the PCBA by the burner. The burner of the invention has six channels, can operate six master ICs simultaneously; the six channels independently set the IC models and the modes of burning, comparision, and reading. The beneficial effect of the invention is that: compared with traditional burners and burning methods, the invention saves burning time, and saves burning procedures; the invention can burn different data on a plurality of ICs; the problem of high data loss rate for traditional burning is avoided; the problem of IC slanting pin mouting caused by traditional IC burning is avoided.

Description

technical field [0001] The present invention relates to the field of Electrically Erasable Programmable Read-Only Memory (EEPROM), in particular to an EEPROM online programming device and an online programming method. Background technique [0002] The traditional off-line programming method is to use a programmer to burn data on the IC before SMT packaging, and then go to SMT packaging. The general method is to unpack the reel package of the IC material first, and the operator uses tweezers to pick up the IC and place it on the Socket of the programmer for programming. Then put the burned IC into a tray or re-package it in reel to facilitate SMT packaging. This is a manual process with low efficiency. In addition, tweezers are often easy to bend IC pins, resulting in quality problems such as empty soldering and poor tin intake (especially for small packaged ICs, the efficiency and quality of this programming method are even worse). In this method, there are many proce...
