Pcb Manufacture And Assembly Lead Free Hasl Rohs Turnkey PCB Assembly
CESGATE SMT assembly welding quality control:
1. The SMT line is equipped with high-end equipments,
high-precision and high-yield processing
2. Quality inspection and control are carried out in each
processing link to prevent defective products from flowing into the
next link.
3. Equipped with a number of quality personnel throughout the
sampling inspection.
CESGATE's advantages of turnkey PCB assembly
As IATF16949 verified circuit board factory, CESGATE will provide
DFM Analysis for your every order , as well as low volume and
medium volume production runs. We verify all details of your files,
including Gerber files, to allow you to correct your PCB design
before manufacturing, saving significant time and cost.
We use ERP and MES system, which can protect all your project files
and also control all the parts quality from the beginning to the
end . As a PCB manufacturer, we have complete and mature tracking
system by the two systems, which can solve the problems quickly,
also guarantees on-time delivery of quick turn printed circuit
board.
Rigid-flex board refers to pressing the flexible circuit board and
the rigid circuit board together according to the relevant process
requirements during PCB proofing to form a circuit board with FPC
characteristics and PCB characteristics; its price is relatively
high, but its use Extremely broad and can be tailored for
applications in many industries. So, under what circumstances does
PCB proofing need to use rigid-flex board?
1. High impact and high vibration environment. The rigid-flex board
has strong impact resistance and can be used in high stress
environments to ensure stable performance of the equipment,
otherwise it will cause equipment failure.
2. High-precision applications where reliability is more important
than cost considerations. If a cable or connector failure is
dangerous, it is better to use a more durable flex-rigid board.
3. High density applications. Some components lack the surface area
required for all necessary connectors and cables. In this case,
using a flexible rigid board can save space to solve this problem.
4. Applications requiring multiple rigid boards. When more than
four connection boards are included in the Turnkey PCB Assembly,
replacing them with a single rigid-flex board may be the best
option and more cost-effective.
