PCBA sample production is a comprehensive test of circuit design, process feasibility and performance stability.

PCBA sample production through small-scale trial, will be achieved three core goals :

1.Verify the rationality of the design: Check whether there are any logical errors,

signal interference, power matching issues in the circuit schematic and PCB layout;

2.Test process feasibility: Verify whether the SMT assembly, soldering, and other processes are suitable for the design,

to prevent process bottlenecks during mass production

3.Evaluate performance stability: Test the sample’s functionality ,thus to various conditions to identify potential reliability issues in advance.

The standard process for pcba sample production

1.Preparatory work: Precise matching of design and components

-Design document : Not only need somplete schematic diagrams and PCB Layout files (including Gerber files, BOM list, coordinate files) must be provided. but also the material of the board , thickness, number of layers , surface treatment process , etc. should be clearly specified;

-Component selection and procurement: Prioritize the selection of components that are easy to purchase and have short delivery times ,

However, it is necessary to ensure that the parameters of key components are consistent with the design ,

Thus to avoid performance deviations caused by substitutes.

-Process plan confirmation: Communicate with the sample factory regarding process details,

such as the SMT soldering accuracy requirements , the welding temperature curve , and the reserved positions for test points.

2.Production Execution: Production + Inspection

–PCB board manufacturing: Produce sample boards according to design requirements, and strictly control the quality of the base plates.Therefore,this is what enables the production of the products that customers truly need.

-SMT Soldering and Assembly: High-precision surface mount machines;

for DIP connectors, wave soldering or manual soldering will be ensure full and solid solder joints without any voids.

-Initial inspection and rework:After welding, we typically inspect the appearance of the solder joints using AOI.

and the multimeter the test continuity of key circuits.

-Electrical performance test: Through ICT,Then can check the components ;

L test parameters such as circuit continuity, resistance, capacitance, etc.

-Function Test (FCT): Simulates the actual working environment of the product,

Thus testing whether the PCBA has achieved the designed functions ;
