Printed circuit boards, multilayer substrates, PCB substrates

 

02.Product Features

1. Function introduction

The impregnation treatment of the substrate is divided into three stages, the pre-wetting device, the impregnation device and the metering device. The pre-wetting device uses a pre-wetting roller to pre-wet the surface of the substrate with epoxy resin. After the substrate is pre-wet coated , And then impregnate the base material in the resin tray, and then measure after the impregnation is saturated, and scrape off the excess resin with two metering rollers to complete the entire impregnation process. The two metering rollers adjust the gap between the two rollers with a master-slave gap adjustment system, and adjust the thickness of the impregnated resin of the impregnated substrate to facilitate operation. Another metering roller can be opened by an air cylinder to facilitate the passage of the substrate. When the cloth head passes through the gap, the air valve can be relieved to allow the cloth head to pass through the gap and then pressurize and measure. The metering roller uses a motor to pass through the belt. transmission. After the metering roller is measured, the residual resin on the metering roller is scraped off with a scraper. After being collected by the collecting tray, it is transferred to the viscosity adjustment tank for further use. The glue pipeline of the impregnation tank is specially designed to reduce turbulence and air bubbles. phenomenon. In the impregnation tank, all the guide rollers are in contact with the same surface of the substrate to ensure the impregnation effect

2. Equipment composition

01 Prepreg machine composition

1. The scraper is made of stainless steel, which can move left and right.

2. It can be glued on one side, dipped on both sides, can be reversed, and can be adjusted independently; there are three ways of prepreg

3. Chain lifting mechanism and the glue tank can be removed for cleaning.

4. The dipping part has a chain lifting system,

02 Main immersion machine composition

1. It consists of three parts: dipping, squeezing (metering) and scraping.

2. The metering roller adopts a high-gloss mirror roller, the metering roller is φ240mm; and it is equipped with imported precision bearing set, active extrusion, and can be adjusted independently for positive and negative rotation.

3. The metering roller gap adjustment is driven by a motor, which can be linked or single-acted from left to right, and can display the gap between the two ends of the metering roller.

4. SUS304 board sandwich tank body design, the tank body can be hot water, and the bottom is more glued.

5. The glue tank and the frame are detachable, and the chain is raised and lowered to facilitate the removal of the tank body for cleaning.

6. Glue tank glue circulation piping + glue back pumping pump set + bag filter barrel

 

03. Technical parameters

1. Applicable substrate: glass fiber cloth 1017, 1027, 1037, 1061080, 2116, 7628

2. The substrate tension is 30 to 50kg

3. Fluctuation after tension control<±4N

4. Pre-impregnated roller machine power 2 horsepower

5. The power of the metering roller machine is 3 horsepower

6. The thickness of the coating on the surface of the metering roller is not less than 0.2mm, the surface hardness is greater than HV700, the surface roughness is not less than Ra0.1, and the dynamic balance accuracy level is not less than G2.5
