Method for manufacturing metal matrix printed circuit board embedded with ceramic chip

Abstract

The invention discloses a method for manufacturing a metal matrix printed circuit board embedded with a ceramic chip. The method comprises the following steps: placing a ceramic chip to holes of a metal matrix; sleeving a RCC, sleeving the RCC which is peeled off a protective membrane to the metal matrix which is placed with the ceramic chip therein; tacking, putting the metal matrix embedded with the ceramic chip to a tacking jig at a speed of 0.6m / min; laminating, curing a resin and at the same time adhering the ceramic chip to the metal matrix; cutting glue-spilling, removing the resin which spreads to the surface from the holes; conducting regular metal substrate procedure. The method manufactures an aluminum base and the RCC separately, achieves accurate manufacturing of the circuit boards, can manufacture a printed circuit boards with embedded ceramic chip that has the high heat conduction property of the ceramic chip and can be manufactured on regular production lines of metal matrix. The printed circuit boards with embedded ceramic chip has high cost performance, wide application potential, has a heat conduction coefficient of 170 W / m.k, and a voltage proof value of 6000 V AC.

Description

technical field [0001] The invention relates to the field of automobile indicator lights, in particular to a method for manufacturing a metal-based printed circuit board embedded with ceramic sheets. Background technique [0002] The names of circuit boards are: circuit board, PCB board, aluminum substrate, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances. Circuit boards can be called printed circuit boards or printed circuit boards. Printed circuit boards are the most active industry in the contemporary electronic component industry, and their industry growth rate is generally about three percentage points higher than that of the electronic component industry. It is expected that the rapid growth ...

Problems solved by technology

[0004] At present, metal-based printed circuit boards with high thermal conductivity include copper-based boss boards (also known as thermoelectric separation copper substrates), ceramic-based printed circuit boards, ALC boards (Chinese: diamond-like carbon printed circuit boards), etc., each product All have certain defects. For example, although the thermal conductivity of the copper-based boss plate is as high as 400W / m.k, the withstand voltage is small, below AC 2500V; the ceramic-based printed circuit board needs to invest in special equipment to make the ceramic substrate, and the cost is high; ALC Board production cannot be shared with conventional printed circuit board production lines, special equipment and special potions are required
