Fine-pitch soldering lives or dies on flux control. HMT-Y046 is a transparent, insulating flux paste in a needle-tip syringe, made for work where a flooded joint is not an option: BGA reballing, micro-soldering, and dense connector work. A tiny dot activates with heat, sharpens solder flow, and dries into a clear, non-conductive film that can stay safely on the finished board.
Why You'll Reach for It on Every Job
See-through paste – the transparent formula keeps pads, pins, and joints visible as you place flux and heat them, so nothing is covered up mid-repair
Non-conductive after drying – the residual film insulates, so fine-pitch pins stay safely separated with no risk of leakage or shorts
Activates on heat – lifts oxides and improves wetting, helping solder snap to pads and form bright, well-shaped joints
Needle-tip precision – dispense flux dot by dot onto BGA pads, IC pins, or jumper wires without touching a brush to the board
Stays in place – paste consistency holds its dot through handling, instead of running across the board like liquid flux
How to Use
Clean the work area to remove dust, oil, and old residue.
Dispense a small dot of HMT-Y046 onto the pads, pins, or joint.
Solder with your iron or hot air – the flux activates with heat and improves flow.
After cooling, leave the clear insulating film on the board or wipe it away for a spotless finish.
Specifications
Model: HMT-Y046
Type: Transparent insulating flux paste in syringe dispenser
Applications: BGA and micro-soldering, fine-pitch IC rework, connector and wire soldering, phone and laptop board repair
Who It's For
A workhorse consumable for micro-soldering technicians, PCB rework lines, and serious hobbyists. Keep a syringe at every station – when precision matters, dot-applied flux beats brushes and bottles every time.
Tip: a flux dot the size of the joint is enough – over-fluxing can wick under chips and make inspection harder than it needs to be.
