How to Produce Electronic Circuit Sample Step by Step

is a small batch pcb trial production before mass production. Only when the  Electronic Circuit passes the inspection 

standards can the mass product be released with peace of mind. 

This method avoids production risks to a certain extent. As an extremely important part of small batch pcb assembly, 

what about the  Electronic Circuit  production process?

Step 1: 

contact the factory

Before starting the small batch assembly of pcb, we need to obtain the printed circuit board sample. 

That is a pcb prototype. Firstly, tell the factory the required size, process requirements, 

product quantity and other relevant data, and wait for the professional to provide a quotation and place an order.

This is the second step of pcb sample production. According to the engineering information provided by the customer, 

cut small pieces of production board on the board that meets the requirements. 

The specific process: large sheet material → cutting board according to MI requirements → curium board → beer fillet / edging → plate out.

The 3 step: drilling

Drill holes on the plate that meets the requirements, and drill the required hole diameter at the corresponding position. 

The specific process: stacking board pins → upper board → drilling → lower board → inspection/repair.

The 4  step: sink the copper

Use a chemical method to deposit a thin layer of copper on the insulating hole. 

The specific process: rough grinding → hanging board → automatic copper sinking line → lower board → dip 1% dilute H2SO4 → thickened copper.

Transfer the image on the production film to the board. 

The specific process: hemp board → lamination → standing → alignment → exposure → standing → shadowing → inspection.

Plating a copper layer with the required thickness and a gold-nickel or tin layer with the required thickness on the exposed copper skin or hole wall of the circuit pattern. 

The specific process: upper board → degreasing → second water washing → micro-etching → water washing → 

pickling → copper plating → water washing → pickling → tin plating → water washing → lower board.

Print some characters on the circuit board for easy identification. The specific process: After the green oil finishes →

 cool and stand → adjust the screen → print characters → rear curium.

After these thirteen steps, the  Electronic Circuit production is completed. Now how to produce a small batch Electronic Circuit Sample ?
