5. While in the test of repairing and changing the chip, the chip should be examined to start with, and after that the operate check shall be done right after passing. The function exam must make certain that the modest heat sink is welded competent. When setting up the massive warmth sink, the floor with the chip have to be evenly coated with thermal gel as well as cooling fan shall be at total velocity.
Open up MPLABIPE and choose device: PIC16F1704, click on power to select the facility offer mode, then click run. The first step: pick file to discover the .HEX file to get programmed; The 2nd action: click on hook up with link normally; The 3rd stage: simply click This system button, and right after completion, simply click verifiy to prompt the verification to prove which the programming is productive. Figure five-seven Figure 5-8 Forth step: Look at the boost circuit output
In the case of a particular chip remaining set, check for irregular resistance welding in the entrance and rear CLK, CI, and BO in the Xth chip. Should the take a look at time is sort of two times as long as the good board, it may reveal a challenge with soldering.
8V ranging from the very first chip. Should the serial port stops long-expression operation once the limited circuit, the main chip is functioning thoroughly.
PatternNG is due to the big distinction between the qualities on the chip and also other chips. At the moment, it is actually observed that the chip die is damaged, so just swap the chip. In accordance with the log info, the substitute procedures are as follows: If the appearance with the chip will not be harmed, just change the chip with the lowest reaction price in Every area. The subsequent figure demonstrates one of several exam logs, it could be noticed through the log that the reaction level of four chips asic[36][37][forty three][seventy five] is reduced.

c-1) Predicament 1: The examination time is basically similar to that of an Alright board (generally the value of X does not improve every time it is tested). (The take a look at time refers to the time from pressing the start check button towards the LCD exhibiting The end result ASIC NG: X).
Common phenomena: IP cannot be detected, the number of admirers is Get It Here abnormal, and also the chain is abnormal. When there is an abnormality inside the test, Adhere to the monitoring interface and test LOG prompts for servicing.
a) After the card recovery is passed, the green LED indicator are going to be constantly on, and the ability shall be restarted;

● Once the plan examination is passed (the brief-circuit check of the general schedule test is necessary to stay away from the chip or other resources currently being burnt due to small circuit when the ability is turned on), the chip check can be performed Using the hash board tester, and the positioning is usually determined based on the check results of the hash board tester. ● According to the displayed results with the hash board tester detection, starting from in close proximity to faulty chip, Look at the chip examination points (CO/NRST/RO/XIN/BI) and voltages which include VDD0V8 and VDD1V8. ● Based on the sign flow, apart from the RX sign, reversely transmit the sign (from No. 76 to No. one chip), a number of with the signals like CLK CO BO RST are ahead transmission (one-seventy six), as well as abnormal fault level are available in the electrical power offer sequence.
