TH vacuum generator repair

After the TH vacuum generator fails, is it still necessary to repair it? Regardless of any faulty problems in the TH vacuum generator, it can be repaired, 

but which one is more affordable, the cost of repair or the cost of replacement. According to our experience of repairing so many sets of TH vacuum generators,

 repairing is more cost-effective than buying new ones. Today, I would like to share with you an TH vacuum generator fault detection and maintenance method, 

remember to collect the useful ones!

The TH vacuum generator is an easily damaged accessory. Many generators have a higher failure rate than other components due to their frequent work 

and unclean air supply circuit during the actual placement process. , so almost every factory has a bunch of broken vacuum generators, which have become 

abandoned fixed assets. We hope that through this article, we can help all SMT factories save a lot of spare parts expenses, which is also to help factories reduce

 A solution to reduce costs and increase profits.

How to quickly detect and repair when encountering a fault

Let me share a maintenance idea of TH vacuum generator. Through the following methods, the fault point can be quickly detected, so as to carry out accurate maintenance.

method:

1. Measuring the sprint: along the power supply input terminal Pin3a/b: 24V; Pin4a: 5V; Pin8a/8b: +15V, the red test lead is connected to the negative, and the black 

test lead is respectively measured 24V/5V/15V Static diode value, see if There is a short circuit;

2. If there is no short circuit in method 1, you can power on and measure the reset pin of the main control chip and the output frequency of the crystal oscillator.
