Description
Products Description
The DH-G600 model is a reasonably priced BGA repair machine, which among the others is the best option for all kinds of PCB motherboard repair. This BGA rework station is automatic, and it has three independent heating zones-top heater, bottom heater, and infrared preheating-which allow for accurate and stable soldering and desoldering.
Optical alignment BGA station DH-G600 (manual camera positioning) also have HD touch-screen control, an automatic cooling system, and a vacuum suction pickup, all of which contribute to the automatic BGA rework station DH-G600's performance in terms of precise alignment and secure chip removal. A perfect option for the pros who want to get the maximum performance at the lowest possible cost.

Operation procedures
1. Desoldering (The Removal Process)
Desoldering is the controlled melting of existing solder to safely remove a faulty chip from the PCB without damaging the delicate copper pads.
Preheating: The station's bottom IR preheater warms the entire PCB. This prevents the board from warping and reduces the "thermal shock" when the top heater starts.
Targeted Heating: The top hot air nozzle moves over the BGA chip and follows a programmed curve, reaching the melting point of the solder.
Reflow & Lift: Once the solder balls reach a fully molten (liquid) state, the station's internal vacuum pump automatically activates. The suction nozzle descends, grips the chip, and lifts it away from the board.
Site Preparation: After removal, the remaining "old" solder on the PCB must be cleaned using a soldering iron and desoldering wick (braid) to create a flat surface for the new chip.
2. Soldering (The Installation Process)
Soldering is the process of bonding a new or "reballed" chip to the PCB pads to create a permanent electrical and mechanical connection.
Flux Application: A thin, even layer of "tacky flux" is applied to the PCB pads.This removes oxidation and helps the solder flow and "wet" the pads correctly.
Optical Alignment: This is where the DH-A2E's CCD camera is critical. You use the micrometer to align the image of the chip's solder balls with the image of the PCB pads until they overlap perfectly on the screen.
Placement: The machine precisely lowers the chip onto the fluxed pads.
Reflow Soldering: The station executes a specific soldering profile.It heats the balls until they melt and "collapse" slightly onto the pads. The surface tension of the molten solder actually helps the chip self-center.
Cooling: After the peak temperature is held for 30–60 seconds, the heaters turn off, and the cross-flow fans activate to solidify the joints quickly, creating a strong, shiny connection.
