Datak Premier® Series, standard types
Printed Circuit Boards coated with Positive acting resist.

The Premier Series boards are one ounce copper on FR-4 Fiberglass substrate. Exposure can be done with and ordinary 100 watt, Edison (household) light bulb.

1.) A conventional white light 100 watt bulb and lamp fixture to hold it.
2.) An exposing frame to hold the positive against the Premier PC board during exposure to the light.
3. ) Developer concentrate; mix with ordinary tap water.
4.) Developer tray: to hold liquid developer and PC board during developing. Any plastic or glass dish may be used, as long as it is large enough to hold the PC board.
5.) Etchant; Ferric Chloride is recommended. Etching should be done in a glass or plastic tray or wide mouth jar (never in metal container).

Standard Premier® PC boards.

    
   The Premier® series is available in various sizes with            copper either on just one side or on two sides.  Dielectric Constant: 3.6 (at) 1 MHz. Step by step instructions are available in this web site.

    Premier® Boards are considered the easiest and safe method. "Printed Circuit Boards for Dummies" was what one customer called them.

    The developer is a very mild sodium hydroxide solution (much like a watered-down Drano) with a small "secret" additive. Remaining developer may simply be flushed down the drain with water and is harmless.

    Below are other weights of PC boards in the Premier series.

Special types include thin (1/32" thickness) boards and standard 1/16" thickness with 2 oz. weight copper.

Special sizes Chart

    To your left, Premier® Printed Circuit boards ready to be exposed to a 100 watt light bulb with your positive art. Note that there are thin 1/32" boards and also boards with two ounce copper.

    Premier boards may be cut with an Xacto style hobby knife; scoring on the cutting line several times usually will permit breaking the PC board into smaller sizes. We suggest that this be done prior to removal of the protective plastic film, but if you work in safe light (red or yellow bug light), you can

    Use Datak no. 12-404 or 12-402 Developer Concentrate ten parts to one mixed with ordinary tap water. This is a liquid supplied in a bottle as you can see at the right.

    The 12-402 is two ounces, the 12-404 is four ounces. Once you have mixed the solution, store unused solution in an air tight bottle. Refrigeration will extend the shelf life, which is ordinarily several weeks,  to several months. The less air in the container, the longer the shelf life. So, a plastic bottle that can be squeezed to reduce air "head-space" will help with storage.

    No. 12-402 Developer Concentrate 2 oz. bottle
    No. 12-404 Developer Concentrate 4 oz. bottle.

    Best results require genuine Datak Developer.

 PC Developing & Etching Trays
    For developing positive boards or etching boards with Ferric Chloride etchant. (NOT

  NOT for use with the Negative developer.)

    Tip: If you make only  small boards, use smaller trays. You will save   on developer and etchant.
 

DRILL BITS for PC board holes
  Two bits per package, except sets 12-530 and 12-550
    These are the common sizes used to drill lead holes for components in the copper pads. Holes should be just a bit larger than the lead sizes.

LAB PC Board ETCHING TANK SYSTEM.

  Like the tanks used by the big producers, except designed for a modest pocketbook and intended for use by users that make a few boards at a time. Etching (with Ferric Chloride Etchant) is vastly more effective when the solution is warm or very warm, agitated and full of air bubbles (oxygen acts much like a catalyst).
The Datak Etching tank system includes a heater to keep the solution warm and a pump assembly (110-120 volts AC) to both agitate and insert oxygen. The System is intended for use on a bench top.

No. 12-700 Complete Lab Etch Tank (does not include the Ferric Chloride Etching solution).
No. ER-12 Power Etch pump and tubing. Includes submersible distributor and may be used in your own tank.
No. 12-704 Replacement hose.
No. 12-702 Replacement Heater (110-117 Volts AC)

FERRIC CHLORIDE ETCHING CONCENTRATE
for etching copper PC boards.

    Supplied in a dry powder form for mixing with ordinary tap water. Convenient in several ways, ships and stores easily and when mixed with water the process creates heat. When used freshly made, the solution will not have to be pre-heated.

    The 1/4 lb. package will produce 1 pint of solution which will etch about 200 square inches of 1 ounce (standard) copper board. Heavier copper, such as 2 ounce, will require proportionally more etchant.

No. ER-3 1/4 lb. Etchant Powder Concentrate
No. ER-21 one pound Etchant Powder Concentrate.
No. ER-22 two pound Etchant Powder Concentrate.

LIQUID ETCHING SOLUTION, ferric chloride.
for etching copper PC boards.

A High quality Ferric Chloride Etching Solution, our preferred solution for all PC board etching.
A quart of solution will etch roughly 980 square inches of standard PC board material.

No. 12-2038 Ferric Chloride Etching liquid Solution 32 ounce bottle.
No. 12-2039 Ferric Chloride Etching liquid Solution, One Gallon bottle.

Pen is filled with a lacquer that may be used directly on the copper board to touch up breaks, add a hand-drawn feature etc; ink will resist etching. May also be used on clear films used for positives to touch up or manually add a trace etc. Black Ink.
