In this colorful world, there are a lot of colors, and these colors affect our preferences and moods, so the resistance of PCB welding can also affect our preferences, each according to their own different hobbies to choose different colors of PCB resistance welding, today we focus on the circuit board resistance often Colors and advantages and disadvantages!
When you recall what color you usually see on a circuit board, yes, there are many common circuit board colors, such as: green and white characters, white and black characters, blue and white characters, red and white characters, black and white characters and so on, and there are some unusual such as: butter and white characters, purple and white characters, you have not found a common point these There's a common word "oil" behind the different colors. You've finally found this little detail. These different colors of PCBs are the common paints in our lives. So the colors on PCBs are the effects of different paints.So you need what color of the circuit board, the circuit board manufacturers just need to use different paint can be produced, so there is no need to use different colors to make different circuit boards, from a cost point of view, only the large amount of conventional ink procurement costs, so the conventional color circuit boards do not need to add. Color cost,
But in the actual production, black oil and white oil circuit board manufacturers will be charged extra, what is the reason? Today I will tell you, black is a very dark color, this color made out of the circuit board is a big challenge to the circuit board, because the dark look is not fine, need to spend A lot of labor costs to check for defects such as appearance, resulting in low labor efficiency, which increases labor costs, which leads to black oil circuit boards a little more expensive than green oil.After talking about black and white, you must say that black is not bright enough to produce more labor costs we can accept, why white is a bright color is also more expensive, there is a question that people explain that the IQ is quite high, listen to me slowly, white is a bright color system, does not affect the artificial Increase, but you should remember that white is a very easy to yellowing color, so in order to make a pure white circuit board, need to increase the white curing uniform, so as to ensure that the white oil does not yellowing, the increase of this addition uniform increases the cost, so it is expensive, if you do not mind the white oil yellowing is not. It will increase the cost. Everyone knows it here.
Okay, today to popularize this knowledge to everyone here, next time in the analysis, surface treatment of the problem!
