two. In the event the EEPROM NG is shown around the Liquid crystal display screen of the hashboard tester, Look at whether the welding of U5 is normal;
d-one) The main situation: the check time is largely the same as The great board (usually the worth of X will never modify each time you take a look at) (exam time refers to the time from when the start check button is pressed to the results of ASICNG: (X) displayed within the LCD). This situation is probably going for being due to the irregular resistance welding of your entrance and rear CLK, CI, and BO from the Xth chip, so end users shall concentrate on these six resistors. The compact probability is due to X-one, X, X+one, that may be, Amongst the three chips, the subsequent pins abnormal welding disorders from the chip manifest: Figure 5-16 d-2) The next circumstance: the test time is sort of twice as long as the good board (from time to time the worth of X will transform when you exam, and sometimes X=0); at this time, the log commonly has the next information (the crimson variety is not really 13, based on which seat the hash board tester is linked to); in the take a look at, suppose the area voltage of all the fields before the abnormal position is nearly less than 0.
② Visually inspect irrespective of whether you will discover obvious indications of burnt areas, sections impression offset or missing elements, and many others.
● Following the regime test is handed (the brief-circuit take a look at of the general regime check is important to avoid the chip or other products being burnt as a result of short circuit when the power is turned on), the chip examination might be performed Together with the hashboard tester, as well as positioning could be determined according to the examination result of the hashboard tester.
Should the chip’s physical appearance just isn't broken, the chip with the lowest reaction fee in Every area must be replaced.
● When finding the defective chip, the chip has to be welded all over again. The method is to incorporate flux throughout the chip (if possible no-clean up flux), and heat the solder joints of the chip pins to a dissolved state to prompt the chip pins and pads to re-run in and acquire the tin, In order to attain the influence of tinning yet again. Should the fault remains precisely the same following re-soldering, it is possible to specifically substitute the chip.
You should watch Price Here out never to believe any impostors, make sure you check our right Get hold of information and beware of being deceived obtaining cheated, and getting rid of revenue. make sure you Verify our correct Get hold of way: In this article
two. Just after there isn't any complications in program testing (brief circuit detection in schedule testing is mostly required to stay away from burning the chip or other supplies as a consequence of shorter circuit when electricity is on), the check fixture can be used to detect the chip, as well as positioning could be determined based on the exam fixture detection final results.
At that time, Microsoft Marketing will make use of your whole IP address and person-agent string so that it may possibly appropriately method the ad click on and demand the advertiser.
4mm); when replacing a whole new chip, you might want to tin the chip pins and after that solder towards the hashboard, then lock substantial heat sinks right after making use of thermal gel evenly to the chip floor.

Evaluate whether You can find output on the second pin of U6 as well as the voltage is about three.3V; if Sure, you should carry on to troubleshoot the condition; if there's no three.3V, make sure you Test the relationship status on the hashboard tester cable and the hashboard is OK, and reprogram the PIC.
The voltage of each voltage domain is about 0.36V. When there is 14V energy provide, commonly it's got area voltage. The precedence is specified to measure the output of the ability provide terminal with the hashboard and whether or not the MOS is brief-circuited (evaluate the resistance involving pins 1, 4 and 8). If 14V has energy provide but no domain voltage, carry on to check.
