Has anyone used a heating station to solder BGA packaged chips? [Copy link]

 

I have to solder a BGA chip to a board recently. In the past, I used to open a steel mesh and use a soldering station like the one in the picture to solder QFN. I'm not sure if BGA will work because the chip is more expensive and I'm afraid the cost of trial and error will be too high.

In my opinion, there is no difference between BGA and QFN packages, both are surface mount. The level of care in hand soldering is related to the price, hahaha

You do everything by yourself? Where? Find a normal BGA board and practice repeatedly.

You can find out how to solder bga chips when you repair mobile phones and laptops.

QFN is not afraid of soldering errors. It will not affect if you pull it off or buckle it down and then solder it. BGA is not so durable. I have not soldered too many pins, so I'm not sure. Do you usually use an air gun?

No matter how expensive it is, it is just a semiconductor chip. It is important to find the right skilled person! How is your FPGA technology now?

I'll ask the mobile phone repairman, but I still think it's more reliable to do it myself.

Enough for your own use

BGA board cannot be practiced and needs ball planting

You mentioned that and it reminded me that decoupling capacitors should be placed on the back of the BGA board. Double-sided SMDs cannot use heating plates.

BGA seems to be tinning the pins one by one. It's quite troublesome. There are videos on Kuaishou and Douyin.

I checked on Kuaishou and found that it requires a steel mesh, solder paste, a hot air gun, a microscope, and a soldering station.

QFN has no problem using this soldering station

BGA needs to get some useless ones to practice first.

The bottom of the BGA is too dense. I guess you are talking about a lot of pins. The amount of solder paste inside must be well controlled, otherwise it is easy to cause cold soldering.

Is the chip soldered?

I have all these tools, but I don't have a reflow soldering machine. I'm not sure about the hot air gun.

Makes sense. Before soldering, I practiced with the ZYNQ FPGA on my scrapped mining board.

The BGA chip has balls. How to control the amount of solder paste if the steel mesh is opened as a whole? Should the diameter of the steel mesh pad be changed?

In planning, the schematic diagram has not been drawn yet

No, normal BGA soldering requires at least a dedicated BGA rework station, and large BGAs even need to be heated on both sides. This heating station can only help disassemble the BGA at best.

It seems that I have to use a heat gun. I am not sure.
