What is BGA workstation?
What is a BGA Rework Station? A BGA rework station is a machine that can be used to refinish or repair printed circuit boards (PCBs) with ball grid array (BGA) packaging and surface-mounted devices (SMDs).
What is an SMD Rework Station?
Surface Mount Device (SMD) rework station is also known and referred to as hot air blower. They are used for soldering and de-soldering of integrated circuit (IC) parts or chips and Ball Grid Array (BGA). It is also used to repair mobile phones and Printed Circuit Boards (PCB).
How much does Reballing cost?
The process involves detatching the gpu or cpu using a very expensive tool then replacing the gpu or cpu dots with a reballing device. This process costs $100, and I need to go to a third party computer repair shop to get my laptop reballed.
How do you rework a BGA?
What are the steps of BGA repair?
- First, remove the components, such as the PCB.
- Next, remove the residual solder.
- Once you have removed all the excess solder, the BGA can be reballed.
- After the excess solder has been removed and the BGA has been reballed, the components and PCB can be re-soldered and reattached.
What is BGA package?
What is a BGA? A Ball Grid Array Integrated Circuit is a surface mount device (SMD) component that possesses no leads. This SMD package employs an array of metal spheres that are made of solder called the solder balls for connections to the PCB (Printed Circuit Board).
Which SMD rework station is best?

Which is the best SMD?
What is the Best SMD Chip?
- 3528 SMD CHIP. The 3.5mm x 2.8mm chip is one of the most popular, due to its cost effectiveness and the fact that it doesn’t give off much heat.
- 5050 SMD CHIP. 5.0mm x 5.0mm are known as having ‘tri-chips’ simply meaning that they have 3 LED diodes in one housing.
- 2835 SMD CHIP.
- 5630 SMD CHIP.
Can reballing fix GPU?
If some connection inside the GPU has failed, reballing is a waste of time and materials, as a reflow would also “fix” the GPU. Also, in most cases the repair (regardless of it’s done by reflow or reballing) won’t last very long, as the connections inside the chip will break again quickly.
Can a GPU chip be repaired?
Repair a laptop graphics card
A graphics card repair should be performed ONLY by a professional PC technician in a lab. Usually the video chip should be replaced. It is a BGA component and can be replaced only using hot air or infrared BGA Rework Station.
How many times can you rework a BGA?
There is no hard industry rule but the rule of thumb for most companies is no more than 5 to 6 thermal cycles at reflow.
What temperature should I reflow my BGA?
If you must use lead-tin solder paste with lead-free BGA packages, ensure that the reflow temperature is high enough to provide a reliable interconnection. A minimum peak temperature of 220°C is recommended, but a range of 225–245°C (for qualified components) is preferred.
How many types of BGA are there?
Technically, these package types fall into three main categories: Ceramic BGA (CBGA) Plastic laminate BGA (PBGA) Tape BGA (TBGA)
What is the difference between BGA and LGA?
Essentially, the most basic difference between the two is that an LGA based CPU can plugged in and out of the motherboard and can also be replaced. A BGA based CPU, however, is SOLDERED on the motherboard and thus cannot be plugged out or replaced. The BGA based CPUs are generally found in mobile devices like laptops.
Can a heat gun melt solder?
Hot air guns produce heated airflow that can melt solder and remove components — like ICs — from PCBs.
Which SMD is the brightest?
In technical terms, SMD 5730 series are the brightest of all. But, do you know what do they mean? Practically, all LED strip lights are provided with certain code names like 5730, 5050, 3014 etc. These numeric terms are basically the physical dimensions of LED strips; for instance, 5050 refers to 5mm x 5mm.
Why is reballing necessary?
Jaywn, reballing is usually performed to replace a BGA IC, not a device. It has become somewhat more accepted to reflow devices like PS3 XBox etc. Most of the time a reflow is based on generally known failures. It is the thermal cycling that causes the following in Lead-Free Solder over time.
What does Reballing mean?
Reballing involves dismantling, heating the chip until it can be removed from the board, typically with a hot-air gun and vacuum pickup tool, removing the device, removing solder remaining on the device and board, putting new solder balls in place, replacing the original device if there was a poor connection, or using …
How do I revive a dead graphics card?
How to revive a dead GPU in the oven #shorts – YouTube
How do you diagnose a bad GPU?
The Main Signs of a Dying GPU
- The Computer Crashes and Won’t Reboot. One moment, your graphics card is running the latest graphic-intense game without a single issue.
- Graphic Glitches While Playing Games.
- Abnormal Fan Noise or Performance.
Can BGA processor be replaced?
No. All those mobile processors (U series) are soldered onto the motherboard. They are BGA parts so they do NOT use sockets like their desktop cousins.
How do you reflow a BGA chip?
How do you solder a BGA package?
BGA Soldering by Hand
- Apply Flux Paste (Not Liquid Flux) on to the pad.
- Place solder balls very carefully on the pad.
- Apply paste flux to the bottom (soldering side) of the BGA package.
- Carefully place the BGA Package on the solder balls.
- Preheat and then apply Hot Air with Hot Air Blower from both top and bottom.
Why is BGA used?
A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package.
What is BGA inspection?
BGA inspection is a process where the connections between a chip and a PCB are analyzed to ensure quality. BGA inspections look at various aspects of the ball grid array, including the package’s standoff height, the quality of the connections and more.
Which is better LGA or PGA?
Durability – LGA socket offers a more durable CPU as the contact pins are on the motherboard socket. On the contrary, PGA socket offers a more durable motherboard as the pins are on the processor. Space Efficiency – LGA pins are smaller than PGA pins and hence, it offers more space efficiency which is always desirable.
