Question: What is the most common quality issue for this kinf of pcb?
Answer: 1) Copper burr in half holes
2) Oxidation in half holes
Question: Why use surface treatment ENIG+OSP?
Answer: OSP has good tin solder paste feature . The BGA size is only 8mil. If use immersion gold, it's not good for tin solder paste. So we suggest customer to use ENIG+OSP. It can protect other pads well and meanwhile, it makes sure that the BGA pads have good tin solder paste feature.
Question: Is the cost for ENIG+OSP higher than ENIG?
Answer: Yes it is. But it won't make a big difference.
Quesion: What is the Silkscreen in a PCB?
Answer: The Silkscreen is the top layer of a Printed Circuit Board (PCB) which is used as a reference indicator for placing components on a PCB Board. It requires a specifically formulated ink whose standard color is white, but it can also be Red, Black, Yellow, Blue and a number of other colors.
The silkscreen is used to specify useful information on the PCB board that can help/assist users during assembly. It is used to mark component values, part numbers, test points, polarity etc.
What is the purpose of using a silkscreen layer?
The silkscreen is not applied to PCB boards by default. A customer has to ask for this and there is usually an additional charge for applying a silkscreen on the board. Here are some important benefits to opt for the silkscreen layer:
There are three main ways to add a silkscreen coating on a PCB board:
