Recently, PCBBUY will launch transparent ink (solder mask) into our new technologies list. It’s the first time in the industry to push transparent ink on PCB. Are you curious about transparent ink? You can follow us and check this passage for the common questions about it. Are you ready? Let’s check it!

1.     What's special about transparent oil?

Transparent ink and green ink, suitable for various industries, simply speaking, just did not add pigment pigments, in a sense, transparent ink resin composition is more pure, delicate and sufficient.

2.     What is the difference between transparent ink and other ink?

What are their performance advantages and disadvantages?

In the performance of the difference, can default to meet the PCB industry IPC standards and test standards.

3.     Which industries use transparent ink?

As far as PCBBUY's existing market is concerned, transparent ink is highly recognized by geek products and naked board and display products customers. Just like a unique show in the electronics industry, that is attractive and ordinary enterprises or manufacturers dare not easily try

4.     What is the price of transparent oil? Is there a discount?

Transparent ink itself has certain cost price difference, the real cause of transparent ink technology product cost is higher is a circuit board for transparent ink in the process of the production process control, because of the transparent ink is completely exposed exposed all plank, lines, such as the most intuitionistic quality, so the internal production control for acme will become more precise and the appearance of the corresponding high scrap rate.

5.      Is the transparent oil made in the factory?

Is our company and the domestic leading ink brand jointly developed and repeatedly tested and verified the withdrawal of new products, other information for trade secrets, inconvenient to talk more.

What is the function of PCB solder mask in manufacturing?

Solder mask or solder stop mask or solder resist is a thin lacquer-like layer of polymer that is usually applied to the copper traces of a printed circuit board (PCB) for protection against oxidation and to prevent solder bridges from forming between closely spaced solder pads. A solder bridge is an unintended electrical connection between two conductors by means of a small blob of solder.

PCBs use solder masks to prevent this from happening. Solder mask is not always used for hand soldered assemblies, but is essential for mass-produced boards that are soldered automatically using reflow or solder bath techniques. Once applied, openings must be made in the solder mask wherever components are soldered, which is accomplished usingphotolithography.Solder mask is traditionally green but is now available in many colors.

Solder mask comes in different media depending upon the demands of the application. The lowest-cost solder mask is epoxy liquid that is silkscreened through the pattern onto the PCB. Other types are the liquid photoimageable solder mask (LPSM) inks and dry film photoimageable solder mask (DFSM).

LPSM can be silkscreened or sprayed on the PCB, exposed to the pattern and developed to provide openings in the pattern for parts to be soldered to the copper pads. DFSM is vacuum laminated on the PCB then exposed and developed. All three processes go through a thermal cure of some type after the pattern is defined.
