Laptop Chip Level Repair Machine
The BGA rework station DH-G600 is a professional laptop chip level repair machine designed for service centres and repair workshops that need consistent, documented BGA rework results across the full range of laptops, desktops, game consoles, and mobile devices — without the cost and complexity of a fully automatic system.
Description
Products overview
When a laptop comes in with a failed GPU, a dead CPU, or a defective bridge chip, the outcome of the repair comes down to two things: how clean the desoldering is, and how accurately the replacement chip lands back on the pad. Get either of those wrong and you are looking at a board that passes a quick power test and fails two weeks later in the customer's hands. The DH-G600 was built specifically around both problems. It is a professional laptop chip level repair machine designed for service centres and repair workshops that need consistent, documented BGA rework results across the full range of laptops, desktops, game consoles, and mobile devices - without the cost and complexity of a fully automatic system.
What sets the DH-G600 apart within Dinghua's rework station lineup is the combination of a Panasonic HD CCD optical alignment system with a three-zone independent heating architecture and a Windows OS control interface. The CCD camera delivers ±0.01mm chip placement accuracy - the same specification you find in high-end automatic stations - while the manual operation mode keeps the workflow flexible and the price point accessible for professional repair operations that do not need full automation.
who this machine is for
The DH-G600 is the right choice for:
Laptop and desktop repair centres doing regular GPU, CPU, and bridge chip replacement - the machine's primary design target
Game console repair workshops handling GPU packages on PlayStation, Xbox, and similar platforms where chip placement accuracy determines whether the fix holds
Mobile phone repair shops that need precision optical alignment for fine-pitch chips on compact boards
ECU and automotive electronics repair operations working on vehicle control units where chip-level replacement is part of the service offering
Military and portable medical equipment repair - the DH-G600 is explicitly cited for these applications by Dinghua, given the process precision and repeatability it provides
Medium and large-scale service centres running a mixed board workflow across multiple device categories
If your operation does BGA rework daily across a variety of board types and chip sizes - and you need the alignment accuracy of an optical system but prefer manual control over the full workflow - the DH-G600 is positioned exactly for that.
key features
1. HD CCD Optical Alignment System
The DH-G600's defining feature is its optical alignment system. The lens extends automatically over the work area, captures a live magnified image of both the BGA chip's ball grid and the PCB pad simultaneously, and overlays them on the HD screen. The operator adjusts the chip position using fine-tune micrometer knobs until the balls register perfectly with the pads, then initiates reflow.
As an optical CCD BGA soldering station, the DH-G600 brings machine-grade placement precision to a manual workflow - which is exactly what separates it from rework stations that rely on laser-only or visual-only positioning.
2. Laser Positioning for Fast Board Setup
Alongside the CCD system, the DH-G600 includes laser positioning that marks the centre of the PCB pad. For repair workshops handling recurring board models - the same laptop model every week, or the same game console GPU job repeatedly - the laser reference point allows fast, repeatable board loading without going through the full optical alignment setup from scratch on every job. The two positioning methods work together: laser for speed on known jobs, CCD for precision on any job.
3. Three Independent Heating Zones
The DH-G600 uses the same three-zone architecture found across Dinghua's professional rework station range:
| Zone | Type | Power | Role |
| Top heater | Hot air | 1200W | Direct reflow of target BGA chip |
| Bottom heater-Zone 2 | Hot air | 1200W | Local area preheating beneath the chip |
| Bottom heater-Zone 3 | Infrared | 3000W | Full-board IR preheating plate |
| Total 5600W | |||
Each zone runs an independent K-type thermocouple closed-loop PID control, holding ±2°C accuracy throughout the complete reflow cycle. The sequence matters: the infrared preheating plate brings the full board to a stable thermal soak temperature before the local hot air zone and top heater activate. This graduated approach eliminates the steep temperature gradients that cause PCB warpage, cracked ceramic capacitors, and tombstoning on small passives near the target chip.
The top heater also includes an airflow adjustment function specifically to reduce hot air volume when working with small or fine-pitch chips - an important practical detail, since high airflow on a small chip can physically displace surrounding passives during the reflow cycle.
4. HD Touch Screen
The DH-G600 runs a HD touch screen, available in both English and Chinese. The interface displays real-time temperature curves for all three zones simultaneously, showing the programmed target profile alongside the actual measured temperatures at every point in the cycle.
Profile storage is substantial - the system can hold a large number of temperature curve groups, each named and recalled instantly. For a service centre running regular jobs on the same board models, this means consistent results without the need to re-enter profile parameters each time. The USB interface allows firmware updates and profile backup.
5. Built-in Vacuum System - Auto Chip Pick-Up
The DH-G600's mounting head includes a built-in vacuum system that picks up the BGA chip automatically after the desoldering cycle completes.
The same vacuum system handles the chip during the re-mounting step, holding it securely in position during optical alignment and through the reflow cycle. This is part of what makes the DH-G600 a complete IC chip reballing rework machine - the desoldering, chip handling, optical alignment, and re-soldering all happen within the machine's workflow, not as separate manual steps between operations.
6. Mounting Head Pressure Protection
The DH-G600 mounting head includes a built-in pressure testing device that monitors the force applied to the PCB during the rework process. If downward pressure on the board exceeds the safe threshold, the system flags it before damage occurs. This is a meaningful safety feature on a manual machine - it protects against the kind of subtle mechanical stress that can crack pads or lift traces on thin or already-damaged boards.
