Fully-finished PCBs with 2 solder-masks

and 1 or 2 silk-screens as needed

Full finish on copper: HASL, RoHs, gold or

silver .

Short lead time at normal charges.

Many technical options available

Many Materials options available

USA PCB prototype |PCB small order

Panel design and stack up design charges

needed

Not IPC standards for prototypes

Random e-test or no e-test for PCB prototype.

NO soldermask or no silkscreen with America or

European PCB prototype/small orders

Long lead time or very expensive prices for quick

turn.

Only one type of techincal option available

Only one one material option available.

Comparisions of Caring Circuit PCB and USA PCB

prototypes and Small Orders

You might think the expensive freight and long shipping times are disadvantages of China

PCB.But in fact, the freight is very cheap to ship from China to all over the world, eg. DHL,

UPS ,Fedex and airfreight around 60% discounted by comparison. Shipping time is only 3-4

working days.

Quickturn Prototyping Time


If you have an urgent requirement for circuit boards in less than

our standard lead-times, we are also here to help. Over the years,

we have pulled some very large rabbits out of some very small

hats for some very grateful customers. If time isn't your constraint

we offer discounts for extended turns

An unbelievably simple approach to order


Step #1: You- Send Gerbers with quantity, specifications, destination, etc. View

details

Step #2: We- Detailed quote in 2 hours (max.10 hours, price, lead time, freight,

standards, etc.)

Step #3: You- Confirm your order and pay. View payment term

All in advance (preferred, it will save bank charges)

30% deposit and balance before delivery against pcb reports and photos of

bare pcb, packages and packing list (OK). View reports and photos format

Step #4: We- PCB layout check and fabrication. View engineering query format

Step #5: We- Reports of fabrication status. View fabrication reports format

Step #6: We- Deliver and send you delivery note. View delivery note format

Just two steps from you

Factory View - Drilling


DRILLING

Caring Circuit has 10 Excellon five spindle

air bearing drilling and routing machines

and 6 Excellon Century 2001 six-spindle

drilling machines. These machines use

state-of-the-art technology to automatically

measure drill bit length, diameter, and

spindle runout each time a tool is changed.

Furthermore, these machines have

continual broken drill bit detection systems

during the via formation process.

Factory View - Plating


PLATING

Caring Circuit has built two custom plating

lines that incorporate all specifications

which minimize plating thickness variation.

These include plating at 17 A.S.F.,

submerged anodes and cathodes, single-

deep panel racks, and dual rectification.

Technically speaking, there cannot be a

better plating process.

FILM & IMAGE DEPARTMENT

Our film and imaging department is housed in a

temperature and humidity controlled Class 10,000

clean room. Caring Circuit has implemented the

MultiLine tooling system, which uses computer-

aided punching systems to insure near-perfect

front-to-back registration.Our LPI soldermask and

LPI legend imaging area is also housed in a

temperature and humidity

controlled area in order to hold .002” tolerances

needed for today’s technology.

Factory View - AOI


A.O.I. - AUTOMATED OPTICAL

INSPECTION SYSTEM

All inner layers with circuits are verified to meet our

customer requirements using an automated optical

inspection system that compares the physical

inspection product with the customer-supplied

gerber files.This guarantees the high reliability of

Multi PCB multilayer circuit boards. Your advantage

with Caring Circuit is that A.O.I. is always

included for multilayer boards! On request, 1 and 2

layer circuit boards can also be tested with A.O.I.

The A.O.I. test verifies the finished conductor trace image for deviations from the Gerber data and

finds errors that the E-Test may not discover, such as (for example) narrowed, but still unbroken

conductor traces.

The A.O.I. test is especially important for the following application areas:

High frequency

High power loads

High data transmission rates

Op-amps with high amplification factors and input resistances

Factory View –Testing


FLYING PROBE (FIXTURELESS)

ELECTRICAL TESTING

For quick turns and short runs, we offer

fixtureless testing with our six flying probe

testers. Since no fixture is necessary,

testing for low volumes is made fixture is

necessary, testing for low volumes is made

possible at substantially lower costs.

Flying probe test is a new solution for PCB circuit testing, and the flying probe test machine

is a system that tests the PCB board in a manufacturing environment. Flying probe test is

very flexible, and its 4 to 32 independent controlled probes will move to the element under

testing limberly. The unit under test will be passed to the testing machine by strap or other

transmission system, and then fixed. The testing machine’s probes will test each element in

UUT (unit under test) through the contact with the test pad and via. When one element is

under testing, the other elements will be masked off to get rid of the readings interference.

E-TEST FIXTURE

ELECTRICAL TESTING

Every circuit board built by Caring Circuit is

electrically tested100% using a net list. All

test fixtures are designed and assembled in-

house using specialized equipment. Having

these processes in-house reduces our

customers’ costs for fixtures by up to 60%.
