In-line In-Circuit Tester SRC-AL308
1. Introduction to SRC-AL308
The connection automatic online test system SRC-AL308 can be used for the automatic test of PCBA after connecting the automatic circuit board assembly production line furnace (wave soldering/ reflow soldering), or it can be connected to the board machine, connection table, NG/OK Buffer separately. The trigger and the lower trigger form the automatic test production line, and its main functions include:
1. It can detect the components on the assembled circuit board within a few seconds: resistors, capacitors, inductors, transistors, FETs , LEDs, ordinary diodes, voltage regulator diodes, optocouplers, ICs and other components. Can meet our required specification range.
2. It can early detect the defects/defects in the PCBA process of the automatic circuit board assembly production line , such as short circuit, open circuit, missing components, reverse, wrong parts, empty welding and other bad problems, and feed back to the front end of the production line, so that Timely improvement of the production process.
3. It can store the above fault or bad information, display or print out the test results, including fault location, standard value of parts, and test value, for the reference of maintenance personnel. This can effectively reduce the maintenance personnel's dependence on product technology, without having too much understanding of the product line, and still have the ability to maintain.
4. Able to count the test bad information and analyze it through production management personnel to find out the causes of various bad things, including human factors, so that they can be solved, improved and corrected, which can improve the ability of circuit board assembly, manufacturing and quality .

● Up to 8 -pin isolation per step, providing the best and most efficient test conditions for components.
● Perfect self-checking function: can check AC , DC , channel board, signal board, I/O card, etc. to ensure that the equipment is in good condition before work, and
Easy equipment maintenance.
● Bar code input: scan the number of the PCB with a bar code to store the test results and provide data for production or maintenance management. (scanner gun additionally)
● Broad View board under test display function, real-time display of fault points, easy to find faulty components.
● Sensitive voltage sensing technology, self-developed TEST-JET technology, can test IC pin leakage soldering open circuit, connectors and so on.
● The combination of the three-pin test leakage current test method covers almost all electrolytic capacitor polarities.
three. Benefits of using an in-circuit tester:
The application of online tester equipment has brought about great changes in the production process and management of circuit boards, which are embodied in the following aspects in the application of enterprises:
1. Greatly increase the production speed and output, and improve the straight-through rate
The application of on-line test equipment solves the bottleneck in production and makes the equipment utilization rate of the production line reach the highest level, so as to obtain the maximum production volume while obtaining a high through rate.
2. Significantly reduce maintenance technicians and their training
Because each online tester only needs to be equipped with a circuit board maintenance worker, and the maintenance worker's task is to troubleshoot the printed faults of the tester without knowing the circuit principle. Thus, the training of maintenance workers is omitted. Therefore, enterprises have greatly reduced their dependence on high-level maintenance technicians.
3. Simplify production quality management processes and methods
Due to the means of immediate detection and statistics of the quality of cartridge placement and welding, the quality of the previous process has been quickly feedback-controlled.
4. Significantly reduce production costs
Since a lot of man-hours, training costs, management costs, material costs, etc. have been saved, the huge reduction in production costs is self-evident.
5. Significantly reduce after-sales service costs and improve corporate market reputation
Before adopting the online tester, a large number of products with hidden faults and temporary good performance came into the market, resulting in a vicious circle of prominent after-sale quality contradictions, sharp increase in service costs, and decline in corporate reputation. However, the online tester can detect and eliminate the hidden faults on the circuit board and ensure the overall quality of the circuit board, so that the above problems can be solved easily.
6. Accelerate the development and production of new products
Online testing equipment enables new products to achieve the goal of stable mass production in just a few days, so companies can quickly launch new products that meet market demand without worrying about organizing production and product quality.
7. Enhance the company's ability to undertake processing business and improve the success rate of the company's horizontal joint venture cooperation
The presence or absence of online testing equipment has now become the key equipment to be inspected by domestic and foreign orderers when looking for cooperative factories. For professional processing companies, having online testing equipment as a means of comprehensive quality assurance and accelerated production can quickly gain cooperation approval.
