PCB processing chemicals

DP50 developer

Kinsten chemicals have been selected and pre-measured for easy use in producing PCBs.

Developer

A sachet of DP-50 developer is mixed with 1 litre of 25°C water. The exposed PCB is gently agitated in solution. The exposed areas of resist will dissolve into the solution, leaving the green resist in areas that were not exposed to UV light.

If the resist does not fully remove from the exposed areas, the UV received was insufficient. Possible causes are: Insufficient exposure time; the UV source is old and not producing enough UV; incorrect UV frequency (use 350~450µm UV source); the artwork is not UV transmissive.


DP-50 packaging is 50 sachets to a bag, and 5 bags to an export shipping box.

When the DP-50 solution no longer develops the resist in a timely manner, it can be neutralised using the Kinsten BV-5 neutraliser kit, converting the developer to a gel for easy disposal.

EB-750 PCB Etchant

Kinsten recommend EB-750 PCB etchant for use with Kinsten boards. If using an ET10 tank, two (2) EB-750 sachets are required for a fill, and three (3) EB-750 sachets are required for an ET20 tank fill.

Mix the sachet contents with warm water until the powder is dissolved. Pour the solution into the etching tank, ensuring that the level is above the Min Level mark on the heater element. Using the air pump to circulate the solution, turn on the heater until the solution is at the operating temperature.

As the etching process increases the etchant temperature, larger PCBs (>300cm² etching area) the temperature should be set to 40~50°C, and smaller PCB's to 50~55°C. The greater the amount of etching, the higher the temperature rise. The maximum etchant temperature should be limited to 60°C.

Lower the boards into the liquid for etching. Carefully remove the boards and rinse in fresh water when sufficient copper has been removed.

EB-750 packaging is 20 sachets to a bag, and 5 bags to an export shipping box.

The BV-1 etchant neutralising kit is available. It is a two part process, the first part removes the copper from the solution (in solution, the copper is toxic), if sufficient is collected it may be able to be sold to a scrap dealer (although this is unlikely to be the case for home users). The second part returns the solution to a near neutral Ph. One BV-1 kit is required per EB-750 sachet. Ensure that the etchant is exhausted before neutralising.

Etching Tank

Kinsten etch tank

Kinsten etch tanks are suitable for etching single and double sided PCBs with most etchants. The thin, vertical standing, design uses minimal etchant. The tanks have graduations for easy measurement.

The Kinsten ET20 tank can etch a maximum PCB size of 23×30cm without heater, or 20×30cm with heater. Use with 2000cc minimum, 2300cc maximum liquid.

Etch tanks include three clips to suspend the PCB in the liquid etchant, and a thermometer to monitor liquid temperature.

To complete the Etch kit add an air pump to bubble agitate the etchant, and heater to maintain optimal etchant temperature, for more efficient etching.

Please ensure you order the correct model for your mains voltage. Broadly, 110V is for North America and some areas of Asia, 220V is for Europe and some areas of Asia, 240V is for Australia & New Zealand. However, your area may have a different mains voltage, so please check before ordering.
