4.How do you test printed circuit board function?
More intensive PCB, higher speed of the bus and analog RF circuit is put forward unprecedented challenges to the test, the function test of the environment need to carefully design, well thought-out test method and the right tools can provide reliable test results. 

When dealing with a fixture vendor, keep in mind these issues while also thinking about where the product will be made, a place many test engineers will overlook.For example, we assume that the test engineer is in California in the United States while the product is manufactured in Thailand.Test engineers will think products require expensive automation fixtures, because of the high factory prices in California, requires the tester as far as possible, but also to use automatic fixture in order to reduce the employment of high technology, high salary operator.But in Thailand, neither problem exists, and it is cheaper to artificially solve these problems, because labor costs are low and land prices are cheap, and big factories are not a problem.So sometimes first-rate equipment may not be popular in some countries. 

Technical level in high density UUT, if you need the calibration or diagnosis may need to be done by manual detection, this is because the needle bed contact is restricted, and testing faster (UUT test with a probe can be quickly collected data rather than the information feedback to the edge of the connector) wait for a reason, so required by the operator to probe on the UUT test points.Wherever you are, make sure the test points are clearly marked.
Probe types and ordinary operators should also note that the issues to consider include:
Is the probe larger than the test point?
Does the probe short-circuit several test points and damage UUT?
Are there any electrical hazards to operators?
Can each operator quickly find the test points and check them?
Is the test point much easier to identify?
How long does it take the operator to get an accurate reading at the test point?If the time is too long, there will be some trouble in the small test area, such as the operator's hand will slide because the test time is too long, so it is recommended to expand the test area to avoid this problem. 

After considering the above issues, the test engineer should reassess the type of the test probe, modify the test file to better identify the location of the test site, or even change the requirements of the operator.
