Reballing Professional BGA Chips Repair Machine
Used to repair or replace the ball grid array (BGA) chips on circuit boards. This type of machine is used when the BGA connections become damaged or loose, causing the circuit board to malfunction. The reballing process involves removing the damaged BGA chip, cleaning the board, and then replacing the chip with a new one using a reballing stencil and solder balls.

Why are circuit boards (PCBs) mostly green?
With so many answers, there is no one reliable. This issue has been raised for several years, such a big industry, did not understand,
so terrible! Since the solder resist applied above is green, why is the solder resist green? Why do you want to mix it with green dye?
Green stains are easier to meet at a low cost, controlling UV light absorption during exposure, and the maximum color difference between
copper pads and leads. Light absorption directly affects the minimum resolution and graphic profile steepness. Chromatic aberration
affects defect detection, whether artificial or AOI. In the early stage of technology development, light absorption is the most important
technical factor, but as technology advances, the ability of photoinitiators becomes stronger and stronger, and there is no need to pay
special attention to the effects of the color of dyes, but cost advantages and habits have already formed. So use green. In fact, it is not difficult,
to understand the principle of UV exposure can understand. Sadly, there are not so many answers to this practice. What does it mean? Domestic
engineers do not have a scientific spirit, do not explore the scientific principles behind the problems, and do not use scientific principles to
guide practical work, which is very bad.
(1) Green ink can achieve smaller error, and smaller area can achieve higher precision, the following is the interception of Gorilla's Fab capability
technical documentation.
It can be seen from the technical documentation that green red blue has higher design accuracy than other colors. In the IC Test Board, I
designed earlier, the pin to fanout via the distance of the device is 6mil, as shown in the figure below, so this way In the case of choosing the first
three colors is the most appropriate. It may be because the design of the IC Test Board often challenges the ultimate ability of the Fab, so I
have never seen colors other than green, blue, and red. Of course, there is absolutely no other color (just I didn't see it).
(2) Green ink has better characteristics than inks of other colors
The above information can be concluded that the green system has better characteristics than other color systems, especially the green plug-hole
characteristics. It may be better to understand the plug hole in the IC Test Board design, basically plugging holes, hundreds of Thousands will be
there. Combined with the technical documentation of Fab above, it is clear why the green can be made with high precision, which is also determined
by the characteristics of green. (3) Checked the website of many solder mask inks, and did not conclude that green ink is cheaper than other color
inks, but I believe that it should be greener than other colors. After all, green inks are more demanding. Shipments are larger and naturally cut costs.
