Frequently asked questions

Why is a customized battery solution beneficial and valuable to a product?

Off-the-shelf solutions are often bulky, aside from not being space efficient, meeting the power requirement of the end product is another challenge.  Therefore, a customized solution will provide improved size, weight, performance while keeping development and production costs under control.

What are other key factors to custom battery solution, aside from performance?

Communication capability, safety and longevity...

When it comes to safety, what are the key design parameters contributing to a safe battery pack, aside from environmental testing?

Always, always follow the original specification provided by the chosen cell manufacturer.  Then design and develop with high regards to voltage, current and temperature management.  When it comes to safety, there is no shortcut...

What is a key knowledge that sets Eastek apart from other competitions?

Prolonged storage maintenance feature - "Deep Sleep" implementation to avoid "bricking" - Ultra ultra low quiescent current drain during off mode by passive and active control mode

Why choose Eastek for your customized battery solution?

We pride ourselves with dedicated focus on Tier 1 and Tier 2 cell supplier network and supply chain management, in order to provide material excellence and production continuity.

Frequently asked questions

What is your maximum print area for a PCBA?

Our maximum print area for a PCBA is 508 mm (X) x 508mm (Y).

Do you just do SMT components?

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.

Can you do a double sided PCBA?

Yes, we can manufacturer both single and double sided PCBAs.

What kind of quality solutions do you offer?

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.

Is your reflow oven capable of handling large components?

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

What is Injection Molding?

Injection molding is a method to obtain molded products by injecting molten plastic materials into a mold, and then cooling and solidifying them.

What molding solutions does Eastek offer?

We provide standard injection, muiti-shot, insert molding, in-mold decoration, for low to high volume production.

Where are Eastek's molding locations?

China and Mexico

What is the largest size part you can produce?

We can produce parts up to 621 square inches.

What is over-molding?

Over-molding is the process that adds a softer touch to molded parts while also improving grip on hand controls and providing water resistance and sound absorption.

Frequently asked questions

What is tool design and fabrication?

Tool design and fabrication is the process used to produce a mold for use in plastic injection molding.

Does Eastek offer a mold warranty?

Eastek offers warranties from 1,000 to 1,000,000 shots.

Does Eastek build injection mold tooling in-house?

Yes, Eastek has successfully built thousands of tools in house.

Does Eastek accept tooling transfers from legacy molders?

Yes, Eastek offers tooling transfer services.

Does Eastek offer fast turnaround mold tooling?

Yes, Eastek offer fast turnaround mold tooling with lead-times starting at 2 weeks.

Frequently asked questions

What's Turnkey Assembly?

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.

What's Turnkey Manufacturing?

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.

What's PCB Turnkey Assembly?

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

Will I need to submit multiple PO's or just one?

No, the benefit to Turnkey Assembly is that all components and services are consolidated within a single PO.

What is the benefit of Turnkey Assembly?

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.
