Product Description

Double Sided PCB Fabrication


With the development of high-tech, people need electronic products with high performance, small size and many functions, which promote the development of Double-sided circuit board manufacturing to light, thin, short and small, with limited space to achieve more functions, larger wiring density and smaller aperture.

From 1995 to 2005, the minimum pore size of mechanical drilling capacity decreased from 0.4 mm to 0.2 mm, or even smaller. The diameter of metallized pore is becoming smaller and smaller. The quality of the metallized holes on which the interlayer interconnection depends is directly related to the reliability of PCB.

With the shrinkage of pore size, impurities that had no effect on larger pore size, such as grinding debris and volcanic ash, once left in the pore, will make the chemical precipitation and electroplating of copper lose their function, and the pore is copper-free, becoming the lethal killer of pore metallization.

JHY PCB is a professional Double-sided circuit board manufacturer and supplier, We have nearly 10 years of Double Sided PCB Fabrication experience,We have very advanced Double Sided PCB Manufacturing Process. Whether it is a Double Sided PCB Board Prototype or a small batch, we can make it perfectly according to your requirements.

Double-sided circuit board manufacturing process

In recent years, the typical process of manufacturing double-sided metallized printed boards is the SMOBC method and the graphic plating method. In some specific occasions also use the process wire method.

1, Graphic plating process

Veneer -> Cutting -> Drilling Benchmarking -> CNC Drilling -> Inspection -> Deburring -> Electroless Plating Copper -> Plating Thin Copper -> Inspection -> (Cn + Sn / Pb) -> Filtration -> Etching -> Coating - Check the plating plate -> plug nickel plating -> hot melt cleaning -> electrical on - detection -> cleaning -> screen printing resistance welding graphics -> curing -> screen mark symbols -> Curing -> shape processing -> cleaning and drying -> inspection -> packaging -> finished.


In the process of "chemical plating thin copper -> electroplating thin copper" these two processes can be used "chemical plating thick copper" a process to replace the two have their own advantages and disadvantages. Graphic Electroplating - Etching Method The double-sided metallization plate is a typical process in the sixties and seventies. In the eighties, the brass coating process (SMOBC) gradually developed, especially in the manufacture of precision double-sided panel has become the mainstream process.


2, SMOBC process

SMOBC board's main advantage is to solve the thin line between the solder bridge short circuit phenomenon, and because the proportion of lead and tin constant, than the hot melt has better solderability and storage.

Manufacturing SMOBC board a lot of ways, there are standard graphics plating minus the method and then back to the lead of the SMOBC process; with tin or dip tin instead of electroplating lead tin reduction method of graphic plating SMOBC process; plugging or masking method SMOBC process ; Addition method SMOBC process. The following describes the graphics plating method and then back to the lead tin SMOBC process and plugging method SMOBC process.

Graphic electroplating method and then back to the lead tin SMOBC process method is similar to the graphic plating process. Only after etching changes.

Double-sided Copper Foil Plates -> Graphic Plating Process to Etching Process -> Drop Lead Tin -> Inspection -> Cleaning -> Solder Mask -> Plug Nickel Plating -> Plug Tape -> hot air leveling -> cleaning -> screen markings -> shape processing -> cleaning and drying -> finished product inspection -> packaging -> finished.

The main process flow is as follows:

Sided copper foil -> Drilling -> Electroless copper plating -> Plating copper plating -> Plugging -> Screen printing (just like) -> Etching -> Screen printing, To plug the hole material -> cleaning -> solder resist graphics -> plug nickel, gold -> plug tape -> hot air leveling -> the following process with the same to the finished product.

The process steps of this process are relatively simple, the key is to plug and wash the plug of ink.

In the plugging process, if you do not use plugging ink plugging and screen printing, and the use of a special masking dry film to cover the hole, and then made into a positive graphics, which is masking hole process. Compared with the plugging method, it no longer exists to wash the hole in the ink problem, but the masking dry film has a higher demand.

SMOBC process is based on the first system of bare copper hole metal double panel, and then application of hot air leveling process.
