High-frequency transformer manufacturing process point one.
Winding:
A to determine the parameters B BOBBIN winding requirements of all the principle of formation of non-overlapping single group C line can be wound to monochrome, dual-color line or winding required to open the lines to the sub-pin dip tin, so as not to wound the wrong D tape affixed across the line must isolate 1 sparse disperse evenly around the full 2 close tightly around the cable uniform 3 groove around the edge of the coil on both sides and maintain adequate safe distance A, B 4. tube length must be sufficient, one end of the stretch into the winding tube within the security tape, on the other side out BOBBIN along the surface, but not close to PIN 5. tape cutting the outermost surface of the core portfolio, cut at the core must be covered. 6 around the duct tape flush with the edge, tape is not skewed, do not fold are not damaged. 7 must be affixed to the bottom line across the tape, to keep the coil across the line and below the insulation.
High-frequency transformer manufacturing process point two.
Wire wrapped around
A thick vertical BOBBIN: 0.8¦Õ line wrapped around a circle above the thin 0.2-0.8¦Õ line wrapped around 1.5 ring wrapped around the following line of fine lines 0.2¦Õ vertical BOBBIN 2-3 ring wrapped around the principles of law: wrapped lines to try to pressure in the end the principle of no more than bumps. B Horizontal BOBBIN: circle about tied 2-3, not sparse around the pressure in the end, so as not to solder burns BOBBIN, if the width restriction and strict specifications when used this way, the line wrapped around the solder after the pressure in the end, then trim PIN, to reduce the width of the transformer. C horizontal (horizontal, BOBBIN the wrapped method: about 2-3 rings wrapped around sparse, do not press in the end to avoid solder burns BOBBIN. Note: If the product has a width restrictions and specifications must bear part of the cut wire wrapped around a special case when , then the line must be wrapped as pressure in the end.
High-frequency transformer manufacturing process point three.
Casing
General location of the casing rules: A Exterior: casing does not end with the PIN of the distance as short as possible, but remember never be wrapped around the PIN on the casing will cause air welding phenomenon. B inside: a boundless wall with flat BOBBIN about 1/2L B has side walls with the length of the casing wall must be in the file. Retaining wall tape (margin tape) and its width and materials can not be replaced, because of its width in the design of transformers and materials are related to safety regulations that require special attention. Retaining wall the width of tape: It normally takes the height of the winding and winding high, to prevent the winding copper wire when stacked in the false wall, but if the core due to installation difficulties sometimes about 1/2-3/4 of the package height, but the wound does not stack the principle in the false wall. Tip: sometimes because there are casing out of line when thick if its thickness will affect the practice can be skipped Lead, this time paying particular attention to the location of the casing , must have sufficient safe distance (depth false wall of width) This point must be further off the walls and sometimes the gap is large because of false walls or copper foil and M / F and around the time, no significant depth determine whether the false wall or line on the M / T must be chosen with the M / T with the width of the safety bar, and every single measurement.
High-frequency transformer manufacturing process point four.
The principle of winding copper,
Generally have the following way: A circle is not escorts line, head and tail can not short-circuit, insulation material between the head and tail isolated B circle escorts line, tape width must be greater than the width of copper, C circle above the copper two intermediate pumping lead D-type extension of copper, three-lead
High-frequency transformer manufacturing process point five.
Cable Management
1) Vertical Cable Management Standards
A thin, thick full-circle above the required management, cable management position between the base and the boss 2 / 3 height (insufficient grounds to increase the number of coils) B thread length can not exceed half the distance and the adjacent legs up to no more than 1mm.
C multiple-line and around the cable management, thread management on top and can not finish an then an additional reason.
D, if casing, the casing is not less than the length of the base
E with different foot cable management trough, the same direction around it.
2) Horizontal cable management standards
A cable management evenly distributed in the feet, thread over at least half of the foot line (less than the number who make up the coil to increase rationale, but can not exceed line of foot length)
B foot cable management from the roots upward spiral and at least one start full circle more than reasonable.
C thread length can not exceed half the distance from the adjacent legs and up to no more than 1mm.
D-line and multiple line around the grounds, thin on top and can not reason an end and then an additional reason.
E with different foot cable management trough, the same direction around the tube and the length can not be less than the base, not near the PIN.
High-frequency transformer manufacturing process point six.
Solder
1) PIN after soldering feet smooth, non-stick foreign body. 2) no more than bump thread. 3) complete BOBBIN after soldering, no capacity loss and short legs phenomenon. 4) weld oil (flux) remains small, no soldering, no short circuit. 5) tape in no loss. 6) welding solder at least full circle. 7) After soldering tin can with a lateral tip. High-frequency transformer manufacturing process point seven.
Combination
1) The core portfolio, flat surface, no skew. 2) BOBBIN, CORE, wiring feet to keep clean, no buildup of impurities and plastic type. 3) recognize a GAP on which direction the CORE. 4) EE, EI, UU type CORE maximum skew is not greater than 0.5mm or 1/10CORE width.
