What Is Durostone Insulating Material ?

November 17, 2024

HONY Plastic provides domestic durostone that can withstand temperature up to 380 degrees and is stable, no deformation, no blistering, no linting, no delamination after oven. The processing performance of durostone is good, no burning of the knife, processing speed can be comparable to the Rauschert durostone.

Durostone is a glass fiber compound; it is specially designed to achieve the different needs of the substrate mounting process.

SMT mounting: Synthesized stone has been proved to be suitable for SMT mounting in the various processes, can be machined to achieve the precision required by the SMT process, and in the continuous soldering cycle to maintain its flatness, the material's low thermal conductivity can prevent thermal contraction of the substrate to ensure the quality of the soldering.

The SMT drag board made of durostone has the following functions;

1、Supporting thin substrates or flexible circuit boards

2、Can be used for irregular shape of the substrate

3、Can carry multiple connected boards to increase productivity

4、To prevent the substrate in the soldering back, the phenomenon of bending wave soldering has a gradually rising temperature in the environment, can continue to maintain its physical properties of the ability to make synthetic stone can be in the wave soldering process, to achieve high-standard results and will not have deformation occurs, to be placed in a short period of time in the 360 degrees and continue to operate at a temperature of 280 degrees in the harsh environment, will not cause the material base layer separation.

Durostone can improve the efficiency of the wave soldering process:

1. To avoid the gold finger or contact holes due to manual contact and contamination.

2. The bottom of the SMT components covered, and then through the standard reflow soldering equipment to do localized soldering.

3. Prevent the substrate from bending

4. Standardize the width of the production line

5. Use multi-molded holes to increase productivity.

Difference between DURSTONE Fixture and DURSTONE Jig

DURSTONE (DURSTONE) jig” and ‘DURSTONE (DURSTONE) jig’ two terms, due to the use of close, so it is often easy to be confused, and even misuse. DURSTONE fixtures focus on working and guiding the tool, while DURSTONE jigs focus on holding the tool in a fixed position. Some devices that perform both functions, controlling and guiding the tool, are also called DURSTONE fixtures, but devices that only hold but do not guide the tool are called “DURSTONE fixtures” rather than “DURSTONE fixtures”. DURSTONE JIG” instead of ‘DURSTONE FIXTURE’.

The role and types of DURSTONE fixtures

DURSTONE (DURSTONE) jig's role is to coordinate and control the position and movement, so that it can produce more accurate quality products.

DURSTONE (DURSTONE) fixture types, DURSTONE (DURSTONE) fixtures can be divided into process assembly fixtures, project test fixtures and circuit board test fixtures three categories. Among them, the process assembly fixtures include synthesized stone (DURSTONE) assembly fixtures, synthesized stone (DURSTONE) soldering fixtures, synthesized stone (DURSTONE) disassembly fixtures, synthesized stone (DURSTONE) dispensing fixtures, synthesized stone (DURSTONE) irradiation fixtures, synthesized stone (DURSTONE) adjusting fixtures, and synthesized stone (DURSTONE) shear fixtures, which can be divided into three categories. DURSTONE shear fixtures; while project test fixtures include DURSTONE life test fixtures, DURSTONE packaging test fixtures, DURSTONE environmental test fixtures, DURSTONE optical test fixtures, and DURSTONE shielding test fixtures, DURSTONE (DURSTONE) sound insulation test fixtures, etc.; circuit board test fixtures mainly include DURSTONE (DURSTONE) ICT test fixtures, DURSTONE (DURSTONE) FCT functional fixtures, DURSTONE (DURSTONE) SMT over-oven fixtures, DURSTONE (DURSTONE) BGA test fixtures and so on.

Management of durostone fixtures

Acceptance → storage → storage → use → return to storage

I. Acceptance of synthetic stone fixtures

1. Check whether the synthetic stone fixture is posted “synthetic stone fixture technical parameters table”.

2. Synthetic stone fixture bracket should be firm, to meet the requirements of use.

3. When testing the first synthetic stone fixture, by the operator in the test machine to check the synthetic stone fixture is not a probe short-circuit, disconnection; synthetic stone fixture to do the opposite of their respective test probes are not crushing the PCB board; check the “synthetic stone fixture Technical Parameters Table” is not the same as the total number of points, such as the number of open circuit, the number of short circuits, and so on.

4. If the test is qualified by the operator to fill in the quality records, in the synthesized stone jig to do marking.

5. If the synthetic stone fixtures in the inspection failed, such as short circuit, broken some problems, the operator should be responsible for the disposal, and fill in the unqualified notification form back to the fixture production team to facilitate the improvement of processing.

II. Synthesized stone fixtures into the warehouse

1. composite synthetic stone jig should be placed on the jig probe with a soft cushion, so that the upper and lower synthetic stone jig probe will not be damaged, and use a plastic bag to completely cover the synthetic stone jig.

2. The new synthetic stone jig (including the change of the synthetic stone jig) should fill in the “synthetic stone jig receiving record form”.

3. After the use of the synthetic stone jig, the operator should be responsible for the immediate return to the position, and with the synthetic stone jig administrator to do the appropriate handover procedures, and register the number of tests and the status of the synthetic stone jig.

4. The new synthetic stone fixture should be placed in the corresponding empty space in the fixture library, generally the same customer, the same page or a unified account; and placed in the same level of the fixture library in the same or adjacent empty space, easy to retrieve.

5. The original synthetic stone jig against the account book should be placed in the corresponding number of the location.

6. double-sided synthetic stone jig in the jig inventory, the upper and lower jig to be placed horizontally, and composite together.

7. Single-sided synthetic stone jig in the jig storage is required to be placed vertically.

Three. Synthesized stone jig storage

1. Need to control the temperature and humidity of the synthetic stone fixture library in a certain technical parameters, temperature control ≤ 35 ℃, 75% RH, is strictly prohibited direct sunlight.

2. Synthetic stone fixtures placed between the cabinet and the cabinet, that is, the width of the aisle should be favorable to take fixtures, but also to maintain the specifications of the fixtures 100mm.

3. The width, length and height of each compartment of the placing cabinet should be designed in accordance with the distance between the width, length and height of the fixtures.

4. For each fixture placed in the cabinet, different levels, fixtures placed on the location of the corresponding code.

5. The code on the jig and place the cabinet on the code is consistent, in storage can be placed directly in the original position.

6. The storage of jigs must be neat, smooth and labeled.

7. Change or cancel the customer should be timely clean up its use of fixtures, from the accounts on the cancellation, and the fixtures will be handed over to the fixtures warehouse administrator for recycling and disposal.

IV. Synthetic stone fixtures for use

1. Fixture management personnel should be based on the instructions of the production process card, the customer, model, and related changes to verify the issuance, check the “fixtures using the account book” for registration, and take out the fixtures in the corresponding fixtures stored in the location of the fixtures.

2. When removing the fixtures should be slightly removed from the side of the fixtures, along the direction of the fixtures placed straight out, such as the top of the fixtures, should be lifted up to take out the top of the fixtures, and then take out the fixtures underneath, the two fixtures should be avoided to avoid collision, to prevent damage to the probe.

3. Carefully remove the plastic bag on the fixture, fold the plastic bag and put it back to the corresponding fixture placement.

4. The operator should mark the date of return and the quantity of use on the “Fixture Record Sheet” after use, and the administrator should verify the inspection and file it for preservation.
