Yes, please contact us with your requirements.
Can you supply products to our specifications?
Yes, we certainly can. Please send us your print or spec sheet for our review.
Does PKI have a certified quality management system?
Yes! Our ISO 9001:2008 certification is valid through 1/31/2018.
Engineering
Do you provide Engineering design services?
Yes, we can. Please contact us for more details.
Can you help us with our piezoceramic applications?
Yes, we can. Call (814) 355-1593 to speak with a Piezo Kinetics Application Engineer.
Manufacturing
What type of in-process inspections do you perform?
Your product is monitored through each step of manufacturing to insure they meet all the customer’s parameters.
How do you identify the positive side of the piezoceramic product?
We typically apply a small dot on the positive face, however we can work with you on your marking requirements.
Assembly
Can the Value-Added Manufacturing department manufacture non-ceramic type assemblies?
Yes, we can. Please contact us to discuss your needs.
Can the Value-Added Manufacturing department assist the customer in the design of assemblies?
Yes, in addition to ceramic experts, PKI’s staff includes personnel skilled in electrical and mechanical engineering, who can assist in the design of assemblies.
In addition to one time deliveries, can shipments be spread out over a period of months or years?
Yes, PKI can set up a manufacturing/shipping schedule to suit our customers.
Can the Value-Added Manufacturing department develop prototypes for customers evaluation prior to manufacturing release?
Yes, we will work closely with our customers to develop the assembly to their satisfaction.
Quality Assurance
What parameters are routinely tested on piezoelectric ceramics?
The following parameters are tested on almost all products:
- Physical dimensions
- Capacitance and Loss Factor
- Resonant Frequency and Coupling
- Piezoelectric d33 coefficient
How are capacitance and loss factor tested?
They are tested on a capacitance test meter (LCR bridge) at a standard frequency of 1 KHz and 1 volt.
What is resonant frequency and how is it tested?
Resonant frequency is defined as the frequency of minimum impedance. Resonant frequency (minimum impedance) and Anti-resonant frequency (maximum impedance) are tested.
How is the piezolectric coefficient tested?
d33 is tested on a piezoelectric test meter especially designed for this test. This meter will also display the polarity orientation of the part during the test so that the proper polarity marking can be verified.
Are all parts 100% tested?
Yes, every part is 100% tested to the customer’s specifications.
May I purchase special test groupings?
Yes, frequency, capacitance and d33 may be purchased as groups, matched pairs etc. Please contact us for additional requirements.
Is recorded data available?
Yes, a customer may specify parts to be serialized and specific data to be recorded and shipped with the parts.
Does PKI have a certified quality management system?
Yes! Our ISO 9001:2008 certification is valid through 1/31/2018.
