Take Flexibility and Performance to New Heights with SF201 Flex
PCBs
For electronics designers pushing the boundaries of thin, flexible
circuits, Shengyi's SF201 flex PCB material delivers unmatched
capabilities.
With a ultra-thin 1mil polyimide core and 12/18/35/70um copper clad
options, SF201 removes constraints and opens up new design
possibilities.
Engineered for high frequency applications up to 10GHz, SF201
maintains exceptionally low loss and tight dielectric properties.
Its Dk of <3.7 and Df of <0.01 ensure even the most sensitive
RF/high speed signals can be routed with minimal degradation.
But don't let the flexibility fool you - this material is built
with the utmost reliability in mind. SF201 boasts superb
dimensional stability, soldering performance and chemical
resistance to stand up to heat, stress and environmental hazards.
It's even UL V-0 rated for extreme safety-critical uses.
A sample 1-layer stackup flexes complex circuitry while keeping a
small 25x21mm footprint. Capable of 3mil trace/spaces, it
supportstoday's tightest design rules. And its patented
adhesiveless construction streamlines processing without
compromising flexibility or yields.
With applications spanning consumer electronics, medical,
automotive and more, SF201 is the go-to choice for innovators
pushing design boundaries. Contact us today to discuss how it can
take your next flexible hybrid circuit to the next level through
unprecedented capabilities in a package this slim. The future is
flex - let SF201 be your enabler.
Quality Policy
Bicheng has developed series of management procedures and
approaches to assure that PCBs are in compliance with the
customers' requirements, inclusive of selection of the vendors,
work in progress (WIP) inspection, outgoing delivery inspection and
customer service etc.
Evaluation and Audit of Suppliers
Suppliers have to be evaluated by Bicheng. In addition, Bicheng
will appraise and rank suppliers every year to guarantee the
materials supplied are meeting Bicheng’s requirements. Furthermore,
Bicheng continuously develop suppliers and supervise them to
improve their quality and environment management basing on the
systems of ISO9001 & ISO14001.
Contract Evaluation
Bicheng shall review and verify customer's requirements to make
sure that we have the capability to satisfy customers' requirements
including specifications, delivery and other demands prior to
accepting an order.
Making, audit and control of manufacturing data.
When customers' design data and specifications are provided to our
market department, Bicheng has to verify all the requirements.
Then, convert the design data into manufacturing data by CAM.
Finally, a manufacturing instruction (MI) is generated according to
the real manufacturing process and technologies for manufacturing
department as the basis for actual fabrication. MI must be reviewed
by independent engineers and QA engineers before issue.
Incoming Material Quality Control
All materials have to be inspected before warehousing. We
established a series of strict inspection procedure and instruction
to control the incoming materials. Furthermore, various precise
inspecting instruments and apparatus guarantee the capability to
judge the material good or not. We issue material with first in
first out principle, and give out “alarm” for the material that
will reach the shelf life to ensure the materials are used up
before expiry.
Control of Production Process
Right manufacturing instruction (MI), comprehensive equipment
management and maintenance and process control, strict WIP
inspection and monitoring as well as working instruction, all those
make the whole fabrication process totally controlled.
Final Control and Inspection
All PCBs have to be gone through the open and short test as well as
visual inspection after passed the specified physical tests. We own
various advanced test equipment including customized, probe flying
test machines to guarantee that each PCB is 100% tested.
Product Delivery Audit
We set up a dedicated FQA department to inspect the PCB products
according to the customer's specifications and requirements by
sampling. Qualified PCBs are going to be packed.
FQA also has to carry out a 100% audit of the warehouse packing and
shipping products, including product number, customer number,
product quantity, shipping address and so on prior to shipment.
Customer Service
We sets up a professional customer service team to proactively
communicate with customers and timely deal with the customers'
feedbacks. We highly focus on customers' needs and to understand
customers’ demands, timely to adjust the policy of customer service
and PCB product requirements.
