Product Description




Welcome to Sato Intelligent Technology Ltd.!


 PCB  Production Process:


1. Contact the manufacturer
First, you need to contact the manufacturer, and then register the customer number, someone will quote for you, the next single, and follow-up production schedule.

2.  Board Cutting
Objective: According to the requirements of engineering data MI, in line with the requirements of a large sheet of plate, cut into small pieces of plate production. Meet customer requirements of small sheets.

Process: Large sheets → press MI curium board requires cutting board → → beer rounded \ edging out board →


3. Drilling

Objective: According to project information on the size of the opening to meet the requirements of sheet metal, the corresponding position are asking drilled aperture.

Process: Laminated pin plate → → → drilling → inspection of the lower plate \ Repair.

4. PTH

Objective: Shen copper is the use of a thin chemical copper deposited on an insulating wall of the hole.
Process: hanging plate → → coarse grinding automatic Shen copper wire under plate → → immersion copper thicker% dilute H2SO4 →

5. Pattern transfer
Objective: pattern transfer image is transferred to film production on board
:( Blue oil flow process): a first surface grinding plate → printing → drying → → → drying print the second side came to light red → Movies → inspection; (dry process): Ma laminated board → → → to stand exposure position → stand → → → check punch Movies

6.Pattern plating
Objective: Pattern Plating is on line graphics or bare copper plating layer on the pore walls to reach the required thickness of the copper layer with the desired thickness of the gold layer of nickel or tin.
Process: The board → degreasing → washing → secondary micro-corrosion → pickling → washing → → washing → pickling copper tinned → → washing → lower plate

7. Stripping
Objective: NaOH solution recede plating resist layer covering the copper wiring layer non bared.
Process: water film: Bays → dip → alkali washing → → scrub off the machine; Dry: put the plate over the machine →

8. Etching
Objective: etching method using a chemical reaction non-line portion of the copper layer to corrosion.

9. Green oil
Objective: green oil green oil film is transferred to the graphics board, play a role in the protective circuit and prevent welding parts on the tin line.
Process: grinding plate → printing photographic green oil curium board → → → red shadow exposure; grinding plate → printing → baking sheet first face printed on the second side → → baking sheet.

10. Character
Objective: The character is a recognizable mark provided easy
Process: green oil curium final stand after cooling → → → tune network printing characters → after curium

11. Gold-plated finger
Objective: the plug fingers coated with a layer of nickel requirements \ gold layer thickness, making it more hardness wear
Process: The board → degreasing → washing twice washed twice with micro-corrosion → → → washing → pickling → copper nickel gold plating → washing →

Tin plate (a process parallel)
Objective: HAL is not covered in oil solder bare copper surface spray a layer of tin to protect the copper oxide surface is not etched in order to ensure good weldability.
Process: dried micro-corrosion → → → preheating → rosin coated solder coating hot air leveling → → → washing-cooled air-dried

12. Molding
Objective: shape by die stamping or CNC machine gong gong that customers need a method of forming an organic gong, beer board, hand gongs, hand-cut
Description: high accuracy data gong board plate with beer, hand gongs secondly, with the lowest hand cutting board can only do some simple shape.

Objective: 100% electronically tested to detect visually difficult to find defects affecting the function of the open circuit, short circuit to.
Process: put the mold plate → → → test → FQC qualified visual inspection → → → Repair defective return test → OK → REJ → scrapped

14. Final inspection
Objective: Through 100% visual inspection plate appearance defects, minor defects and repair, to avoid problems and defective plates outflow.
Specific workflows: incoming information → → View → a visual inspection and checking → → FQA qualified packaging qualified → → → treatment failure → Check OK
