Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a circuit board field especially relates to a multilayer circuit board pressfitting is with fixed tool.
[ background of the invention ]
The circuit boards are classified into three major categories, i.e., single-sided boards, double-sided boards, and multilayer circuit boards, in which the components are concentrated on one side and the wires are concentrated on the other side of the most basic circuit board. Such a circuit board is called a single-sided circuit board because the conductors are present on only one side thereof. The single panel is generally simple to manufacture and low in cost, but has the disadvantage that the single panel cannot be applied to a product which is too complex, the double panel is an extension of the single panel, and when the single-layer wiring cannot meet the requirement of an electronic product, the double panel is used. The multilayer board is a product developed from electronic information technology to high speed, multifunction, large capacity, small volume, thinning and light weight.
The circuit board generally adopts the form of multilayer, needs to adopt special circuit board pressfitting machine to carry out pressfitting between its layer. Most direct power device pressfitting circuit board that adopts of current circuit board pressfitting machine, like patent application number: CN202023017429.1 discloses a circuit board compression fittings, place the circuit board in the standing groove, promote the pressfitting board through the cylinder and carry out the pressfitting to the circuit board in the standing groove, during the pressfitting, the circuit board in the standing groove is in free state, can't carry out spacing fixed to the circuit board before the pressfitting, when each layer resin melts, lead to the relative position between layer and the layer probably to take place relative displacement after the pressurized, lead to the bad problem of counterpoint super tolerance between the layer, also some circuit boards are placed and are not carried out the pressfitting fashionable location to the circuit in the location frock, as patent application number: 202120026815.2 discloses a circuit board pressfitting location frock and circuit board semi-manufactured goods, it places the district to form the circuit board through setting up many slot type reference columns and many circular reference columns on the dish is carried to the pressfitting, laminate the location to the circuit board through the reference column, the circuit board shifts when avoiding the pressfitting, but when this structure pressfitting, the reference column interferes the pressfitting board pressfitting easily, when the pressfitting board is to the circuit board pressfitting promptly, the pressfitting board must set up and is placing the district inside, during the pressfitting, the pressfitting board can't carry out the pressfitting operation to circuit board border laminating position, lead to behind the circuit board pressfitting, the circuit board border has the perk, the problem of deformation produces.
The utility model discloses it is not enough to provide to study to prior art promptly.
