Description
Automatic BGA rework machine for car cpu repair
A CPU is the core of ECU, with enough resources and knowledge, the ECU can be repaired,but to diagnose and fix
the faulty component requires a lot of testing, specialized equipment,and depending on the what caused the failure ,
how many components are damaged and what components are needed to be replaced etc. If CPU repaired, a BGA
rework machine is necessary to use, and automatic rework machine with optical CCD alignment system is better choice.
For CPU repairing, the model DH-A2E is great one:

| Right IR switch | Turn on/off |
| Lower nozzle | To collect hot-air for heating |
| Light | Lighting |
| Start of light | Turn on/off |
| Laser position | To locate fastly |
| CCD brightness | Brightness adjusted |
| HR adj. | Hot-air flow adjusted |
| Angle rotating | Chip rotate |
Monitor screen
Both motherboard's soldering pads and chips dots can be imaged on the liquid crystal display, shown different colours
in orde to be easy to overlap.
Chip picked up and Vacuum
Chip-feeder is automatic for chip carrying out and back,vacuum and upper nozzle are 2 in 1, which can vertically
pick a chip up or replace a chip on motherboard.
Joystic of BGA rework macine for car cpu repair.
The joystic designed for a palm can totally hold for zoom in or out when aligning at manual status.
In addition, the upper head going up or down can be controlled by the joystic as well when manuall.
Micrometers for aligning
Repeatable accuracy is up to 0.01mm, motherboard can be moved to left or right and rear or back 15mm,chip's angle
can be turned about 60° .
Heating for soldering
Hybrid heating inclduing hot-air and infrared heating for bottom, to make motherboard protected from not being even heated.
Related knowledges about BGA rework machine:
Surface-mounted devices and printed circuit boards (PCBs) with ball grid array (BGA) packing can both be refinished or repaired using a BGA rework station (SMDs). The experts can replace any missing parts in the PCBs using these rework stations, or they can remove defective pieces and restore them in the wrong places. Rework stations can also be used to
work on PCBs that have other SMDs, chip scale packages, quad flat packages, land grid array packaging, or column
grid array packaging. Therefore, SMD rework stations or surface-mounted technology (SMT) rework stations are named
for BGA rework stations as well.
The size of the PCBs that can be reworked, as well as the kinds and amount of jobs that may be done, are determined
by the features of each BGA rework station. For instance, for simpler operations, BGA rework stations without split-vision functionality work best, but those with it work best for more difficult jobs. Additionally, some rework stations are fully automated, others require complete manual labor.
