As the EV industry pushes forward with lightning speed, the world cannot ignore the potential and significance of the ever-popular Lithium secondary category, which contains the choices of Lithium Ion, Lithium Polymer, and Lithium Iron Phosphate.
While this new and current generation of chemistry provides a higher operating voltage level and energy density, lower self-discharge rate, the biggest win is about significant size reduction to make the end device smaller and lighter. Lithium Iron Phosphate stands out with a larger size and weight characteristics but offers unmatched high discharge current capability, with better safety and life span performances.
While there is no one size fits all chemistry, it is vital for a company to identify the most critical areas of benefit that will trade-off against the loss.
Lithium Ion (Li-Ion) cells have a negative electrode (anode) made from lithium compounds. Lithium is a highly reactive material and is much lighter than the hydrogen-absorbing metal alloy of the NiMH negative electrode. This leads to higher gravimetric energy densities for the Li-Ion cell. Cells can stay in storage for 12 months without requiring maintenance. The expected cycle life of a Li-Ion in an application is about 500+ full charge and discharge cycles.

Lithium Polymer Ion batteries provide the performance of the Li-ion in a thin or moldable package. They do not use a volatile liquid electrolyte and can sustain significant abuse without explosion or fire. The lithium-polymer uses a polymer gel electrolyte to replace the traditional liquid electrolyte. Lithium-polymer finds its market niche in applications that require thin geometries, such as batteries for cell phones, tablets, wearable technologies, and other such applications. The expected cycle life is about 500+ full charge and discharge cycles.

The lithium iron phosphate battery is a type of rechargeable battery based on the original lithium ion chemistry, created by the use of Iron (Fe) as a cathode material. LiFePO4 cells have a higher discharge current, do not explode under extreme conditions and weigh less but have lower voltage and energy density than normal Li-ion cells.
Iron (Fe) is an intrinsically safer cathode material than Cobalt (Co). The Fe-P-O bond is stronger than the Co-O bond so that when abused (short-circuited, overheated, etc.) the oxygen atoms are much harder to remove. This stabilization of the redox energies also helps fast ion migration. Only under extreme heating, generally over 800C, does breakdown occur which prevents the thermal runaway that typical Li-Ion cells are prone to.
LiFePO4 is highly resilient during oxygen loss which typically results in an exothermic reaction in other lithium cells. No PCM is needed but recommended to maintain cycle life and capacity.

Our maximum print area for a PCBA is 508 mm (X) x 508mm (Y).
We have the ability to do through hole components with manual, wave or selective soldering capabilities. We also have the ability to conformal coat, ICT, X-ray, program, automated torque screw insertion and a variety of other secondary operations.
Yes, we can manufacturer both single and double sided PCBAs.
We offer Solder Paste Inspection (SPI) & Automated Optical Inspection in our process. We verify that the correct amount of solder paste is laid down and in the correct area. After the reflow oven, we use the AOI to inspect for a wide variety of component inspection criteria, including Foreign Object Debris (FOD) across the PCBA.
Our reflow ovens are equipped with a total of 13 heated zones, 10 conventional zones and 3 IR zones for heating. Our oven profiling prior to any production runs through the reflow process ensures that the temperature profiling is met to meet industry quality standards.

Frequently asked questions
Turnkey refers to a product that is ready for immediate use for the buyer. What it implies is that CM is offering a comprehensive, ready to go product fully assembled and tested, delivered in retail packaging.
Turnkey Manufacturing usually defines a company that can handle ALL aspects of engineering and manufacturing. It means that they can lead your product from conceptual design to product realization and mass production.Often, the term is used to describe a contract manufacturer that specializes in production only. A customer that uses a contract manufacturer would need to have complete, finalized designs in order to have CM to introduce the product to manufacturing.
Turnkey PCB Manufacturer is a definition that applies for manufacturer capable of providing fully populated PC Board Assembly. That includes fabrication and preparation of PC boards, procurement of electronic components, populating PC boards, continuous monitoring of quality and life of your PCB Assembly. Life of your PCBA is defined by terms related to individual components that make PCBA, i.e.:
LTB = Last Time Buy
EOL = End of Life
No, the benefit to Turnkey Assembly is that all components and services are consolidated within a single PO.
When you partner with a turnkey manufacturer, you only need to manage one vendor, which can save you the delays and miscommunications with separate vendors, if you outsourced them yourself. Usually, there will only be one single point of contact. Having to manage multiple vendors can sometimes be overwhelming.
