1.3.Capabilities
Our testing capabilities are listed below in Table 24:


2.Flying Probe Test
The Flying Probe test method makes use of electro-mechanically controlled probes to test points on a PCB one at a time. This electrical testing method is more suitable for testing low-to-mid-sized quantities of physically smaller PCBs. The Flying Probe method boasts a lower associated cost, compared with the Fixture method, since no expensive programming or fixture setup is required. This meticulous method offers greater accuracy, which translates into increased fault coverage and defect detection over other testing techniques. The drawback to this method is an increased time required for each individual board test, which stems from the fact that the probe must move through the board in a specific sequence.
At Hopetimepcb,we consider the standard threshold for deciding the electrical test type to be 15 manufacturing panels. We will use Flying Probe if order quantity is less than 15 Manufacturing Panels or if the PCB order in question has an area smaller than 1 square meter

3.Fixture (Bed of Nails) Test
The Fixture (Bed of Nails) test method dictates that a test template be created, with pins aligned to the test points in the circuitry of the PCB. Test templates, or fixtures, are made by first inserting pins into holes on an epoxy phenolic glass-cloth-laminated sheet. Each pin is aligned for an instant connection with a test point in the circuitry of the PCB, and all pins are fixed permanently. When a bare PCB is pressed down against the fixture, stable connections can be instantly and simultaneously formed with hundreds of test points within the circuitry of the PCB. This testing method requires an investment of time and material cost to create the initial fixture but allows for very rapid testing after that fixture is created.At Hopetimepcb , we consider the standard threshold for deciding the electrical test type to be 15 manufacturing panels. We may choose the Fixture method if the order quantity is greater than 15 Manufacturing Panels, or if the PCB order in question has an area greater than 1 square meter.

4.Cost
At Hopetimepcb, we perform two different types of electrical testing, and the associated cost differs between the two. These two types of tests are known as the Fixture method and the Flying Probe method.The Fixture method, also known as Bed of Nails, requires that a template be created, which will then be used to test each PCB in turn. Building this template, or Fixture requires time and additional costs for the necessary materials, but can test large numbers of PCBs very rapidly. At Hopetimepcb, we offer a standard test price on the condition that your design incorporates less than 1,300 test points. In the case that your design boasts over 1300 test points, we will calculate the price depending upon the number of test points required on the fixture.
The Flying Probe method does not require expensive materials for the building of fixtures; instead, a machine sequentially connects electro-mechanically-controlled probes to individual test points on a PCB. This method is not well-suited to very high volume orders due to the time required to the probe to learn the testing sequence, and also to actually move through each board during testing. Since the time required for a Flying Probe test can vary so widely depending upon the design in questions, our cost for this testing method will be calculated depending on the PCB’s physical size and layer count.Hopetimepcb performs 100% electrical testing on all bare PCBs produced at its facilities, and this is included in all quotes unless otherwise specified.
