Hemeixin  PCB advantages
 

Structure of Flex PCBs

1. Single-sided: Conductor on one side of the Flex PCB only

2. Double-sided: Conductor on both sides of the Flex PCB, connected with vias

3. Multi-layered: Unlike rigid PCBs which usually have even layer counts only, Flex PCBs can have an odd number of layers. Flex PCBs with three or more layers allow more complex wiring.

 Flex PCB Ordering Advice
If you choose adhesiveless electro-deposited copper as the base conductor with ENIG surface finish. Silkscreen text which overlaps ENIG pads will be made as hollow cut-outs in the pad.
Exposed connector pads should be ≥ 0.2 mm from the FPC's edge. Areas closer than this limit will be removed.
Stiffener and EMI shield are optional additions. These should be described by an individual Gerber layer or a separate CAD drawing, annotated with the material and thickness required in the case of stiffeners. 

Benefits of Flex PCBs

1. Small and lightweight: Suitable for devices requiring high-density assembly, small form factor, and high reliability.

2. High flexibility: Can be arbitrarily bent and moved; simplifies assembly of interconnects by replacing regular cables, especially on moving parts.

Sample for PCB assembly 22-25 orders/day  and SMT Production Produces order 5000000 Point/day
 

Q1.What is needed for PCB PCBA quotation?

PCB : Quantity, Gerber file and Special requirements(material,surface finish , copper thickness,board thickness...)

PCBA: PCB Specifications, BOM,  (Testing documents...) Quantity

Q2. Are my files safe?

We protect the intellectual property for our customers in the whole process Your files are held in complete safety and security... All documents from customers are never shared with any third parties.   

We are willing to promising to keep customers data in high confidential level and sign NDA effect by customer side local law

Q3. MOQ?

There is no MOQ In hemeixin (1PCS is ok ). We are able to handle Small as well as large volume production with flexibility.

Q4.Shipping cost?

The shipping cost is determined by the destination, weight, packing size of the goods. Please let us know if you need us to quote you the shipping cost.

Q5. What service do you have?
A: We mainly focus on PCB +Assembly +Components sourcing service. Additionally, we can also provide testing, cables, enclosure assembly service.

Q6. Can we inspect quality during production?

Yes, we are open and transparent on each production process with nothing to hide. We welcome customer inspect our production process and check in house.

Q7. What is your testing policy and how you control the quality?

For sample, usually tested by flying probe; for PCB Volume over 3 square meters, usually tested by fixture, this will be more faster. Due to there's many steps to PCB production, we usually do inspection after every step.

Q8. No PCB file/Gbr file, only have the PCB sample,can you produce it for me?

Yes,we could help you to clone the PCB.  send the sample PCB to us, we could clone the PCB design it and make Gerber files and Bom

Q9 If we can have sample before quantity order for pcb and PCBA

Yes , we can offer sample to you for confirm and then quantity to produces

Q10 If you accept OEM/ODM And added our logo or UL on pcb or pcba

Yes accept just send us details of your logo or UL number that you need

Q11 What is payments that you accept

-Wire Transfer(T/T)
-Western Union
-Letter of Credit(L/C)
-Paypal
-Credit Cart 
-after that we learn each other more can accept 30 net days payments
