American Circuit Services

Why PCB Brokers use our test service:

PCB manufacturers often rush to get their product in shipping and sometimes they compromise testing requirements. So, PCB brokers use our testing service to add confident to their products before shipping to their customers. Some customers like to test 100% of the order to be re-tested to insure their product is good. With very inexpensive test cost relative to very expensive components it makes sense to retest the full order. Some customers like to test partial orders for example 10 percent of the total order to give them confidence that their boards are made according to their design.

Benefits of using our service:

• Insure your boards are 100 percent functional to your design.
• Avoid wasting expensive components.
• Avoid delays from going your product to market just because of bare board testing was not performed properly.
• We help to build your quality standards and reputation.
• We don't need to compromise quality to complete the order (quantity).
• We are independent to say "PASS" or "FAIL" whatever it is unlike the interest of Manufacturers to complete the order.
• You don't need to pay test fixture cost if you change your supplier because we keep your test fixtures ready when you need them.
• It allows you to import low cost bare boards from oversees and yet provide a quality products to your customer.

As you must have faced nightmares of bare board failing after components assembled, due to compromised testing standards. We can test your boards with your standards.

Some common defects found in assembly:

Bare board testing on fixtures involves using 100 percent resistance test with netlist created from your gerber files. Testing is done on the grid testers with test fixture designed for your medium to high production orders. We have double density grids which allows very dense test areas to be tested on the fixture.

Benefits of testing on fixtures:

• Very fast
• Cost effective
• 100 percent resistance testing
• No adjacency limitation

Capacity of testing on the test fixtures:

We can test from 50 Volts to 250 Volts, We can test continuity resistance at 10 Ohms and isolation resistance at 100 Mega Ohms.

Also called flying probe test which is performed by four moving probes with high accuracy and speed. Flying probe is mostly chosen for low to medium production or prototypes jobs.

Benefits of testing on probe:

• No test fixture cost
• Minimum setup time
• Can handle minor mis-registration of image
• High accuracy for micro test points
• No grid limitation
• Can use resistance and capacitance or both

Capacity of testing on the moving probe:

On flying probe we are capable of testing from 30 Volts to 1000 Volts. We can test continuity resistance at 3 Ohms and isolation resistance at 1000 Mega Ohms.
