Stripper for positive and negative photoresistsThis product mainly consists of caustic soda. It helps removing positive as well as negative photoresists from the PC boards. Compared to stripping with solvents, it gives you two main advantages: Less appearance of odours and safe and entire removal of any organic rests on the board which could spoil subsequent wet processing steps. After the PCB was stripped, it is rinsed under tap water and being neutralized. As a side effect, all traces of etching liquid and copper will be removed from the board and from the final rinse water. Use 50-100 g/litre of water to prepare a stripper for positive presensitized boards. Delivery unit: 250g bag.
Developer for positive presensitized boardsThis developer ensures to get best results with our presensitized boards. It comes in special safety bags. The contents of one bag should be dissolved in 1 litre of water at room temperature. The shelf lilf of the powder is nearly unlimited, the liquid developer can be stored for some weeks in closed bottles, but only for a few hours in an open tray. Delivery unit: 1 bag for 1 l of water.

We recommend to use this product in our machines. Since beginning of 2012 the 56% conc. granulate is no longer available. As an alternative we offer a 40 % liquid solution . The solution has more than 50 g/l copper capacity and etching rates of about 30 down to 10 µm/minute.
You can dilute the 40% liquid solution with 450ml water per litre down to 30 %. With our tests the fastest etching rate was achieved with a 30 % solution.
Dissolve 100 to 250 g of powder completely by stirring in 5 liters of water. The powder dissolves better in warm water. Keep the fresh solution in a well-closed container. Place the object to be cleaned or the piece of clothing in the liquid and let it act for approximately 10 minutes until the stains are no longer visible. Rinse the clothes thoroughly and wash in the washing machine.
In order to selectively remove individual stains a small amount of powder can also be applied directly to the affected areas and moistened well with water. The effect is improved by rubbing with a damp sponge. Wear protective gloves when working.
Close the can immediately after removal! Formation of lumps by absorption of (air) moisture! Do not rush, do not throw!
Delivery unit: 1 set for 2.5l of water. link to manual
Tenting resistFor our Dry film laminator RLM 419p we offer a high resolution dry film as etch resist. The rolls have a width of 304 mm and a length of either 25m or 152m. The tenting etch resist has a thickness of 38μm and is embedded between a separation and a protection foil. The resist is hardened by UV-light. The non-exposed areas are removed with an alkaline developer.
Informationen to other sets of chemicals for surfaces (e.g. ormecon-tin or ENIG (electroless nickel gold)) or multilayer (e.g. Desmear und Sealbond) can be obtained upon request.
To all our chemicals we supply material safety data sheets (MSDS). The MSDS can be downloaded in our customer area.
