three) Endeavor to update the flash system with SD card;In case the Handle board card Restoration machine must start off Usually, the subsequent two ways are needed:
Investigating the serial port log, if 0 chips remain identified presently, It'll be certainly one of the following circumstances:
Ahead of screening the pattern, the repaired hashboard will have to awesome down ahead of testing; in any other case, it's going to cause screening NG.
six. The repaired hash board really should be analyzed using a test fixture, and it must pass over two times to get judged as an excellent product. For The 1st time, after replacing the components, watch for the hash board to chill down, utilize the check fixture to test, and when is passed, place it on a person facet in advance of cooling down. The second time, look forward to the hash board to cool down entirely prior to testing.
PatternNG is a result of the large difference between the properties from the chip and other chips. At this time, it is uncovered the chip die is destroyed, so just switch the chip. In accordance with the log facts, the replacement policies are as follows: If the looks with the chip is just not broken, just change the chip with the lowest response charge in Every area. The following figure reveals among the list of test logs, it might be found through the log that the reaction price of four chips asic[36][37][43][75] is reduced.
Sample NG is a result of the large difference between the properties from the chip and also other chips. At this time, it really is located that the chip die is harmed, so just switch the chip. According to the log information, the substitution policies are as follows:
Routine maintenance technique: During the PT2 test, look at the serial port print log. It is frequently because of an mistake within the sign up deal with of a certain chip. Just exchange the BM5 chip as revealed in Figure five-19 (asic commences from 0).
Open up MPLABIPE and select machine: PIC16F1704, simply click electric power to pick out the facility provide manner, then click on operate. The initial step: decide on "file" to discover the .HEX file to become programmed; the second stage: simply click "connect" to connect Ordinarily; the third step: click the "method" button, and right after completion, click on "confirm" to prompt the verification to prove the programming is prosperous.
(two) Utilize the exam fixture on the V2.1010 Command board (its product is ZJ0001000001), the positive and unfavorable poles of the power source with the exam fixture have to be set up by using a discharge resistor, and it is usually recommended to make use of a cement resistor of twenty five ohms and higher than 100W.
